How can I make ModelSim run faster?
First you can decide to watch only few signals, so that the calculation will run faster. You just need to separate your design into smaller modules (or only look at one process after one). Doing this for every counter can really make you save time. And finally you can obviously accelerate your clock too.
How do you change the simulation time on ModelSim?
I have Questasim, but I remember they have the same GUI.
- Go to Tools in the toolbar, and Edit Preferences.
- Go to the second tab named “By name”.
- Clic on Exapnd all, then on Find…
- Enter the default value of time that your simulator has, check Value in Field, and clic on Find next.
What is simulation speed?
The simulation speed (or the simulation ratio) is how fast RoboDK simulates a real motion. A simulation ratio of 1 means that a movement that takes 1 second on a real robot will take 1 second to simulate. Speeding up the simulation increases this ratio to 100.
How to speed up ModelSim simulation with FPGA?
The syntax is vsim -t ns for nanosecond resolution. Note that the Verilog timescale is very different in VHDL. Since time is a unit in VHDL, the time reference nature of timescale isn’t meaningful (all wait for have an explicit time, not implicit like Verilog’s # ).
How long does it take to run a 1ms simulation?
It takes 45 minutes to get to 1ms as of now. I want the simulation to run for 20 ms to check on certain counters, timer modules and events. The system clock runs at 50 MHz.
What’s the best way to speed up Simulink simulations?
In Simulink ®, there are three desktop simulation modes: Normal, Accelerator, and Rapid Accelerator. For most models, Accelerator is faster than Normal, and Rapid Accelerator is faster still. Rapid Accelerator mode speeds up simulation by generating an executable for your model.
How does rapid accelerator mode speed up simulations?
Rapid Accelerator mode speeds up simulation by generating an executable for your model. The exact speedup varies depending on the model, but Rapid Accelerator can be more than 10 times faster than Normal mode.
