It is possible to probe signal tap using
pre-synthesis or post-fitting results from quartus.
This is actually not correct,
if you run compile only, you cannot probe the "pre-synthesis db".
if you run synthesis, then you are able to probe the "pre-synthesis db".
So signal tap: pre-sythesis
shall be named post-synthesis.
No. Pre-synthesis refers to signals exactly as they are defined in your HDL code. You don't need to perform full synthesis to get pre-synthesis signals for Signal Tap. Just run Analysis & Elaboration, which does not perform any synthesis. The compiler checks your HDL files and makes the pre-synthesis signals available for assignments like in the Assignment Editor and for tapping in Signal Tap.
So by selecting "signal tap: pre-sythesis", I still need to run a synthesis,
as originally posted, correct?
Which is strange to me, as Quartus properly compile and elaborate the RTL + the VQM without problem,
so it shouldn't required a synthesis.
As you stated, VQM is already synthesized, so why having to run the synthesis step again in quartus to include it in the elaborated database?
