## Purpose: This file is really from Digilent, and so the copyright
|
| 8 |
|
|
## statement below applies only to those changes that have been
|
| 9 |
|
|
## made to modify it to support the CMod S6 SoC project. That said ...
|
| 10 |
|
|
##
|
| 11 |
|
|
## This file specifies the pin connections for all of the peripherals
|
| 12 |
|
|
## connected to the Cmod S6 SoC.
|
| 13 |
|
|
##
|
| 14 |
|
|
## Further, this file is *specific* to the main ZipCPU build. Apparently,
|
| 15 |
|
|
## two top level files require two ucf files, so this file applies to the
|
| 16 |
|
|
## main ZipCPU build, and the other file to the alternate, auxiliary build.
