xlsx/schematics mismatch #133

Closed sbourdeauducq closed 4 years ago

sbourdeauducq commented 4 years ago

The .xlsx file with the FPGA pin assignments for v2.0rc8 (production) does not match the schematics.

This shows FPGA pin E28 assigned to DDR3_32_DQS3_N: https://github.com/sinara-hw/Sayma_AMC/releases/download/v2.0rc8/Sayma_AMC_FPGA_pins.xlsx

This shows FPGA pin E28 assigned to DDR3_32_DQ5: https://github.com/sinara-hw/Sayma_AMC/releases/download/v2.0rc8/Sayma_AMC.PDF

Which one corresponds to the boards that have been produced?

@gkasprow Can you PLEASE be VERY careful about this sort of thing? This recurrent pattern has been causing us a lot of problems.

I traced back what happened. After I moved from EE to ALtium, the translator mirrored the schematic symbol. So, all DDR32 pins are mirrored in the xlx file. During routing, I noticed that and fixed. The xls file is very old (March 2019). I have forgotten to generate the new one. I updated the xls file in the release https://github.com/sinara-hw/Sayma_AMC/releases/tag/v2.0.1

Is this 2.0.1 tag still applicable to the v2 boards that have been already produced? What are the differences?

gkasprow commented 4 years ago

Yes, only xls file was not updated.

@sbourdeauducq https://github.com/sinara-hw/Sayma_AMC/commit/75b020da3583e4195b526ac2c1a2b15560f89bde

Boards that were already produced were modified with those changes.
