ModelSim-Altera refers to ModelSim-Altera Starter Edition and ModelSim-Altera Subscription Edition. I don't know what to do to make it "uuuuu." and accept binary value.īeside that i'm getting this warning when start simulation ModelSim, ModelSim-Altera, and QuestaSim Guidelines Quartus II Handbook Version 13.1 November 2012 Altera Corporation Volume 3: Verification 1 Inthischapter,ModelSimreferstoModelSimSE,PE,andDE,whichsharethesame commands as QuestaSim. I.e at the wave window, when i right click my input port and choose force, "32'hXXXXXXXX" is wrote in the value field. I'm trying to simulate my vhdl file using modelsim but actually it is taking the input value in hex format.
