DDR3 Corrupted data (sometime)

olivier faurie

Other Parts Discussed in Thread: TMS320C6678

Hi Experts,

In one of our custom board, we are using a TMS320C6678 with a 2Gb DDR3 UDIMM from Samsung.

So far it is working fine at the DDR3 max speed of 666MHz, but sometimes (around 1/100) we got data corruption when reading back. A DSP Reset solve the issue.

I suspect a "false positive" leveling as DDR3 memory controller status says all is success.

We are working in partial-automatic leveling, and all PCB traces respect the TI spec compensated skew matching rules (1mil skew max in our design).

Any suggestion of the source of the problem, or workaround?

Thank you by advance.

Olivier.

Oliver,

Are you using the latest version of the PHY_CALC spreadsheet? We recently revised this spreadsheet. The revision was specifically to resolve occasional failures as you describe.

Tom,

Thanks for your answer. Actually, we were using "DDR3 PHY Calc V10.xlsx" and "DDR3 Register Calc v4.xlsx" (download from TI website on November 2012). So far, if I don't make mistake, we are using the latest version. Can you confirm?

Thank you,

Olivier.

Oliver,

Those are the latest spreadsheet versions. Can you attach a completed PHY_CALC spreadsheet?

Dear Tom,

You can find the PHY_CALC file we are using here:

6472.lelveling_coeff.xls

I also forward the file we constructed to compute all the compensated trace values:

1385.DDR3_Trace_Length_compute.xls

5875.addr_ctrl_cmd_length.xls

We are using a standard 2GB 1333 UDIMM module from Samsung (Containing 8x SDRAM of type K4B2G0846D).

By the way, after some extensive test sessions we find out that the corrupted data pattern is mostly always the same:

If corruption happens, it concerns the MSB of every DW odd address.

For example we write from address 0x80000000 some random data:

12345678 9ABCDEF FEDCBA9 87654321 ....

we read:

12345678 xxBCDEF FEDCBA9 xx654321 ....

With xx either 00 or random data. Sometimes, corruption happen not on the MSB, but on (MSB-1).

Any workaround to solve this 2% of DDR3 fail?

Thank you by advance.

Olivier.

Olivier,

I quickly reviewed the attachments. I will review them in more detail shortly. Meanwhile, I need more information.

How did you determine the velocity at the top of the PHC CALC sheet? Is this for the board or the UDIMM? It seems high. What material are you using for your base board? Is the UDIMM made from standard FR4?
You are using INVCLKOUT set to 0 in the PHY_CALC sheet. Does this match the configuration software/GEL? Do you get the same failure pattern if the PHY_CALC sheet uses INVCLKOUT set to 1 along with the proper changes to the configuration?
You provided length detail for all of the ADDR/CMD/CNTRL/CLK nets and the DQS nets but not for the DQ and DQM nets. Can you provide this as well?
I assume the UDIMM is one of the standard JEDEC "raw card" topologies. Can you tell me which one?
Are all of the DATA class nets routed adjacent to a solid ground reference plane? Are all of the ADDR/CMD/CNTRL/CLK nets routed adjacent to either a solid ground reference plane or a solid VDDQ/DVDD15 reference plane? If so, which one. Do any DDR traces cross a split in its reference plane?

Tom,

I'm going to reply you as clear as I can:

1.How did you determine the velocity at the top of the PHC CALC sheet? Is this for the board or the UDIMM? It seems high. What material are you using for your base board? Is the UDIMM made from standard FR4?

The value of the velocity had been computed from the Dielectric Constant (Dk) given by the PCB specification document we use for our custom board. We use standard FR-4. Document only claims Dk= 4.6 @ 1MHz. Do you advice us to reduce it to catch the 667MHz frequency?

2.You are using INVCLKOUT set to 0 in the PHY_CALC sheet. Does this match the configuration software/GEL? Do you get the same failure pattern if the PHY_CALC sheet uses INVCLKOUT set to 1 along with the proper changes to the configuration?

Yes, it matches with my GEL file and software. I can make a try to see if DDR3 is working well with the inverted clock features, but it's going to take me some time to make a fail test as we need to reprogram the I2C EEPROM.

3.You provided length detail for all of the ADDR/CMD/CNTRL/CLK nets and the DQS nets but not for the DQ and DQM nets. Can you provide this as well?

This file will be provided to you. but all DQ/DQS/DM are matched with 1 mil within a byte.

4.I assume the UDIMM is one of the standard JEDEC "raw card" topologies. Can you tell me which one?

The UDIMM used is a standard DDR3 module from Samsung you can buy in every computer shop. It's a so-called JEDEC "raw card factor A" (SIngle rank, No ECC, not buffered and 8x SDRAM Module), and we used JEDEC UDIMM spec files to got the trace length. Also timing data had been double confirmed by reading back the UDIMM SPD EEPROM.

5.Are all of the DATA class nets routed adjacent to a solid ground reference plane? Are all of the ADDR/CMD/CNTRL/CLK nets routed adjacent to either a solid ground reference plane or a solid VDDQ/DVDD15 reference plane? If so, which one. Do any DDR traces cross a split in its reference plane?

Yes, We bring great care during the layout. All DDR3 traces are referenced to adjacent solid ground planes, and there is no split. By the way, we also did at that time DDR3 High-speed simulations (PCB+ UDIMM Model) to double confirm timing and signal integrity. So far, the DDR3 High speed verification tool give us success results.

Thank you.

Oliver,

Do you know the dielectric constant for the SO-DIMM? Is it also made of standard FR4?

The other answers match my expectectations. I look forward to your test results when you change your spreadsheet and configuration to use INVCLKOUT=1.

Tom,

Some update of our DDR3 issue:

We turn on the INVCLKOUT features and did some tests:

Result is even worst that before. The kind of data corruption is same as before but will touch different byte (mostly, MSB of every even byte-address). Failure rate is around 12% by testing the first KByte each time. I also tried with 2 different Stripline delay (181.1 ps/inch and 170ps/inch). Both give back similar fail result and rate.

=>We don't understand why failure rate is even higher when we turn on the INVCLKOUT, as document like sprabl2a claims that it can help the leveling.

INVCLKOUT=0 but with different Stripline Delay:

New test had been done with 170ps/inch. It give same kind of error and same failure rate (around 2%) as with 181.4ps/inch. We are also looking for our PCB manufacturer to get more precise Dielectric coefficient at 666MHz.

For our UDIMM module, we don't manage to find out the dielectric coefficient of the PCB used. If UDIMM manufacturer use HF grade FR-4, coefficient can down to 3,6...

Any Suggestion? Thank you.

Oliver,

These results do not make sense and they are inconsistent with the results we have seen from many customers. We must be overlooking something fundamental. Please provide a capture of the results from your test program. I would like to see the test pattern that you are writing and the incorrect data that you are reading back. Also, please explain the algorithm of your test program. Is it a single-location write-read test? What is the size of the data word? Have you performed a block memory test? I not, I recommend that you implement a test the writes 256 locations with a predictable pattern of unique values and then reads it back. Please provide a dump of this result. If you re-run the test, do you see failrues at the same locations or does it move randomly?

This information will help us characterize the mode of failure.

Tom,

Please find more information related to the algorithm:

Test is done each time on the first 4KBytes of the DSP's DDR3 area ( 0x80000000 to 0x80001000) and SRIO port is used to access the DSP:

1-We write the first 64x DW address with non predictive DW random data.

2-Once ready, we read back the same 64x DW.

3-We compare the writing with the reading back result:

If no error found, we increment the address of 0x100 and test the next 64x DW address test. until reach 4KBytes if no data corruption.
If mismatch found, dump file is then updated and written. DSP is then power reset and testing sequence restart from beginning.

4- If whole 4KBytes block tested without error, DSP is power reset and loop test restart from beginning. Dump file is not updated.

=> Is provided both dump file for INVCLK enable and INVCLK not enable.

8764.DDR3_Dump_INVCLK_ON.log

When an error is detected, dump file write the system error time, the loop test number, the DSP's DDR3 address section where the error is found.

Then, it shows the 64 DW written following by the 64 read back DW for comparison.

As you can figure out, error can have different forms within the time or even within the block. Written continually a DW which show error (without reset the DSP)will always read back with one Byte corrupted on both "00" or moving random data.

By doing some more check into the DDR3 result, we also find out 2 more potential issues that can maybe help you to figure out what happen:

Just after a DSP power reset and I2C boot (with DDR3 Init), the DDR3 section read back value via the emulator are not always equal to 0xFFFFFFF. Here is a capture:

However, no data corruption had been detected when we write/read the cells which are not equal to 0xFFFFFFFF. non 0xFFFFFFFF address cell seems to come randomly.

Also, on our 2GB UDIMM DDR3 Module, only 1GB can be accessed. if we write into the 1GB~2GB section, it will just over write the same address on 0GB~1GB section. The most important bit is not taken.

Hope it can help you to figure out.

Thank you!

Olivier.

Oliver,

Your log is very hard to read and to extract errors. Can you add some indication of where the errors are located? In many of the rows the error is in byte 2 or 3 on every other 32-bit word. This equates to byte lanes 6 and 7 on the SDRAM UDIMM. However, on other rows I was unable to identify the failures. It is importanct that we characterize all of the failures. Since you log them as long rows in the text file, can you then add a row with underlines for the errored bytes?

Your test does not attempt to discriminate between read and write failure. Whenever a block read is declared a failure, can you read it again to see whether you read the same values?

Each of your log entries shows the 4K block loop counter and starting address for the 256-byte sub-block boundary. Can you also display on that row the contents of the DDR3 Memory Controller Status Register at address 0x21000004? We need to verify that none of the leveling timeout bits [6:4] are set and that the IFRDY bit [2] is set.

I noticed that every error block in the INV_CLK off log started at the first block 0x80000000. However in the INV_CLK on log I see block entries like 0x80000300. Does this indicate that the previous blocks read back correctly? This is odd. The rows I reviewed had errored bytes in the repeating positions indicating a problem with a single byte lane. However, the first block should have shown the problem. Please review your test code and make sure it is working truly as you intended.

The initial data read from the SDRAM array prior to initialization is indeterminate. This result is not significant.

If your memory is wrapping at 1GB rather than the expected 2GB there must be a misunderstanding in your configuration. Are you using single or dual rankd UDIMMs? Are you setting the IBANK, EBANK and PAGESIZE correctly? These are the only ways that the memory size would appear wrong. This is discussed in section 2.5 of the DDR3 Memory Controller User Guide.

I noticed that I do not have a copy of your completed REG_CALC spreadsheet. Can you provide that REG_CALC?

Do you see this same failure pattern on every board tested? How many boards have you tested?
