A modern hardware definition language and toolchain based on Python
This RFC is a continuation of #381 . Currently, in order to change the shape of a signal, the following workarounds are needed: * for truncation, use `v[:new_width]` * for...
I have a board that has some inverted differential pairs broken out to a connector. The connector is used on several boards and there are daughterboards that can be plugged...
We currently do not have a way to define an explicit relationship between a clock and another user-generated clock, derived from the former. The relationship would be expressed in terms...
Adding `Assert` support in pysim would be helpful for migrating LiteX code that relies on Display statements. While not equivalent to the Display statement, it would give enough information to...
