**force s 1 0, 0 100 -repeat 200 -cancel 1000**įorces signals to alternate between values 1 and 0 every 100 time units until time 1000.Ĭancellation occurs at the last simulation delta cycle of a time unit. txt input and output is in the 10 bit binary data as text as shown below. Preceding the "-r" must be placed in curly braces. do files EDITOR Optional Specifies editor for edit cmd MODELSIM. Once ModelSim launches, we should see this screen (Figure 1):Figure 1. This chapter guides you through the basic steps for setting up an HDL Verifier session that uses Simulink ® and the HDL Cosimulation block to verify an HDL model.
Note Neither the prompt at the beginning of a line nor the Modelsim 10 command set inputs manual#
Adding & starts the ModelSim process in the background so you can continue to use the terminal/command line. ModelSim Reference Manual, v6.5e 11 Chapter 1 Syntax and Conventions Documentation Conventions This manual uses the following conventions to define ModelSim command syntax. When I used modelsim alot more, I used to put all my commands (setting up special waveforms, analog display modes, color divides, etc, as well as the final 'run 10 ms' command in a single file with a simple name like 'z', then just keep running 'do z' from the modelsim window command line. You can find out more if you read the manual: ModelSim SE Command Reference. Or if you want a more advanced way of doing this, assuming your time is set to 1ns: force clk 0 20, 1 20 -repeat 100. Similar to the previous example, but also Use -64 flag when running vsim to use 64-bit version of the ModelSim software. In ModelSim the command to force a signal is: force signalname value time. This cycle repeats starting at 100 time units after the current simulation time, so the next transition is to 1 at 100 time units after the current simulation time.
Modelsim 10 command set inputs simulator#
Here is the extract from that file: force input1 0įorces input1 to 0 at the current simulator time.įorces bus1 to 01XZ at 100 nanoseconds after the current simulator time.įorce bus1 16#f bus1 to 16#F at the absolute time 200 measured in the resolution units selected at simulation start-up.įorces input1 to 1 at 10 time units after the current simulation time and to 0 at 20 time units after the current simulation time. You can find out more if you read the manual: ModelSim SE Command Reference Or if you want a more advanced way of doing this, assuming your time is set to 1ns: force clk 0 20, 1 20 -repeat 100 In ModelSim the command to force a signal is: force signal_name value time
