Perform test implementation for wcsp package #152

Closed secworks closed 6 months ago

secworks commented 6 months ago

We should check that we can implement the current TKey device in the tiny WCSP package available for iCE40UP. Basically create a new constaint file with update pin mappings and run build.

Test build performed 2023-12-21.

Created pin constraint file based on @dehanj layout. Removed all I/Os we don't use. updated Makefile and ran test build. Worked directly. Get 20+ MHz timing and about the same number of LCs (which should not be surprising).

Closing this since the test build has been done.
