Vsim schematic doesn't work (PULPissimo)

[kgf]

No.. the version is OK. Technically it is better to use vopt as a separate step and not let it be called implicitly through vsim. You get better control over it. This is now more than 10 years old. Back in the day, Modelsim changed to a two step compile process (I believe starting with version 6.0 or so) from their older single step process. To make the transition transparent, they added this implicit vopt stage so that people that wrote scripts in 2004 or so, would not have to make any changes.

For a reasonably sized design, it makes more sense to do two separate tasks
vopt options
vsim

As for your question, I am not sure anyone here tried the feature you mention, personally I have never used it. But 2019.1 should be recent enough to have everything working properly. Some of the posters used much older or the AE version, which ended up being an issue (mainly for assertions and SV features).
