TMS320C6657: DDR PHY Calc v11.xlsx for 36-bit on C665x

RandyP

Part Number: TMS320C6657

In the DDR PHY Calc spreadsheet, there is a comment in the Notes tab that v11.0 adds a tab for C6657, but there is not a tab for it. Is there a newer spreadsheet that does include that tab? Or for the C6657 configuration for 36-bit?

The last block of *_SLAVE_RATIO values on the PHY CALC tab specifically says "Not valid for C665x".

Which registers should be used and which values when using the C6657 with ECC?

Regards,

Hi Randy,

I've forwarded this to the c66x hardware design experts. Their feedback should be posted here.

Randy,

Explicit support is available in PHY_CALC v11 for C665x devices. This is evident in the Instructions tab and in the PHY CALC tab. The comment in the revision history is misleading as there is no separate 'tab' for C665x. Be sure that you have column B visible when entering track length values in the PHY CALC tab.
