Detect missing full view of a provided macro

[kareefardi]

Prompt

When including a macro inside a design, a user has to specify a gds and a lef for that macro. Often, one misses a gds file resulting in a final gds with an abstract view of the macro in the final hardened design which is usually not intended.

Proposal

Somehow detect a missing gds file in the preparation stage before running the flow, or capture the warning producing by magic and warn the user about it after the fact.

Implementation suggestions:

• array length comparison
• check for matching file name (- file extension)
