Function Documentation

◆ fixupAllModules()

void fixupAllModules ( InstanceGraph instanceGraph)

This is the root method to fixup module references when a module changes.

It matches all the results of "to" module with the results of the "from" module.

Definition at line 1423 of file Dedup.cpp.

References builder, fixupConnect(), circt::firrtl::getNumPorts(), and circt::firrtl::Out.

◆ fixupConnect()

void fixupConnect ( ImplicitLocOpBuilder &  builder,
Value  dst,
Value  src 
)

This fixes up connects when the field names of a bundle type changes.

It finds all fields which were previously bulk connected and legalizes it into a connect for each field.

Definition at line 1397 of file Dedup.cpp.
