WebMay 2, 2024 · Reading VHDL signal values in tcl. To read signal values in ModelSim, you can use the “examine” command. We can for example read the value of the trigger signal by using this command in the ModelSim console: VSIM 6> examine /trigger # 0. You would want to assign the value to a Tcl variable when using “examine” in a script. WebChange your procedural for-loop to a generate for-loop. for (genvar i =0; i < channel; i ++) begin initial begin force a.b.c.g [ i] .d.e.rst_n =0; #10ns; release a.b.c.g [ i] .d.e.rst_n; end end. Generate for-loops get expanded at compile time, so [i] becomes 8 different constants.
