WEBENCH Error on Import with Orcad Schematic

Other Parts Discussed in Thread: TPS56121

I have created two supplies using a TPS56121 regulator. One is 3p3V and the other is 5p0V. The 3p3V one imports correctly from the EDF to a DSN file in orcad. The 5p0V supply will not import. I have attached the zips I received from the Web Bench tools and the log file of the imports. Does any one have an idea what I am doing wrong? Why did the same supply with the 3p3V output function correctly and the 5p0V one fails. I also tried to kill the Web Bench and restart it but no matter what i try I always get the same edf file back.

Hi Kim,

What version of Orcad Capture are you using?

16.5, but remember that the 3p3V version imported and loaded correctly.

Hi Kim,

After you download the exported zip file from WEBENCH, unzip the file and replace the EDI@CAP configuration file with the file that has been attached. There has been a pin to pin spacing constraint that has been addressed using the configuration file. You can use this configuration file for other designs that get exported to Orcad(R) from WEBENCH(R) until we do a release to fix this. This should enable you to open the schematic in Orcad(R). After you open the schematic, replace the GND symbols in the schematic with Orcad ground using Place->Ground. You should see two grounds in this schematic. One at the bottom of the schematic and one connected to Csnubber_1. Replace both the grounds.

Geralk,

The EDI@CAP fixed my problem with the imports. Thanks for the update on grounds.

Regards,

Kim
