litex/build/lattice/diamond, platform: allows users to add custom sdc files #2113

Closed trabucayre closed 3 weeks ago

trabucayre commented 3 weeks ago

With the current diamond support all timings constraints are written into .lpf This mean it's no possible to assign constraints to internal OSC or PLL outputs.

As a Workaround this PR allows users to provides one or more sdc files to integrate to the project.

Future work is to integrate sdc generation as done for radiant.
