9 years agoTricky, other than VHDL code, I use a PLL, dual-port RAM (inferred M9K), dual port ROM (inferred and uses M9K) and embedded multipliers. I'm not using any DDR at the moment.
Based on FvM's comment, I removed the PLL and "manually" generated the clocks for RTL simulation. This did in fact fix the problem of the simulation failing, but did not speed things up even at "-t 1ns". I am getting a warning:# ** Warning: Design size of 28692 statements exceeds ModelSim-Intel FPGA Starter Edition recommended capacity.
# Expect performance to be adversely affected. which is odd since my code is only a few hundred lines. I was under the impression that libraries were not included and the paid version only gives a 33% performance boost as described here: https://www.altera.com/products/design-software/model---simulation/modelsim-altera-software.html (https://www.altera.com/products/design-software/model---simulation/modelsim-altera-software.html) but maybe I'm misunderstanding it.
