Add CmodA7-35T #9

Thanks for contributing to this project.

Please split your XDC file into one file per logical interface.

splinedrive commented 1 year ago

I can split but is their a naming convention regarding pins?

Paebbels commented 1 year ago

Have a look at KC705.

I saw LEDs in your file, so that would be GPIO.LED.xdc file with CmodA7_GPIO_LED... pins.

Btw. don't comment out pins, they can be all active.

Commenting is not needed because:

by adding multiple XDC files, you "activate" the matching interfaces like LEDs, buttons, Ethernet etc.
in Vivado you can disable a file to deactivate an interface.

Furthermore, by having logical pin groups in files, you can also have matching pins timings or other clock and placement constraints close by, so others won't miss adding them to the project.

Oh, and you can read in the projects documentation e.g. starting here: https://hdl.github.io/constraints/Structure.html
