Unused signals in Modelsim

Hi newsgroup users,

maybe you can help me on the following question:

Does Modelsim remove registered signals which are unused or not connected to output pins? Is there a possibility to avoid this without using output pins?

Kind regards

Modelsim does not remove undriven/unused signals; a synthesis tool, however, is likely to.

It doesn't for the standard level of optimisation. If you enable

-O5/-fast then it may well do.

You can either compile with the default optimisation level, or use an option like +acc to make sure it retains a particular net/register.
