Zachary Snow 3b2a55a69c better error message for indexed atoms 2023-06-18 22:18:20 -04:00
Zachary Snow e09aea48e0 type inference for localparams performed lazily
The implicit type of a localparam is not always needed. This improves
performance when complex localparam expressions are processed.

Zachary Snow 84edbae503 preliminary scoped errors with approximate source location
- scoped traversals can now raise errors which contain the path of the
  current scope and an approximate source location based on preceding
  trace comments, if available
- initially, this new error messaging has only been added for the
  illegal size cast checks in the TypeOf and Cast conversions
- error suite tests can provide a verbose mode expected source location
