Xilinx ISE : How to make Modelsim reload when design changed |
|
|
I've been experimenting with ISE Webpack, and have managed to create a simple schematic, and got the
output waveforms in modelsim,
however what I can't figure out is how to get modelsim to reload the new data when I change the
schematic -
After I change the schematic and do 'create schematic symbol', the only way I can get it to simulate
the new file is to close and re-launch modelsim - surely there is an easier way...? 'Restart'
doesn't seem to do it. |

If the changes are already compiled,
try this from the modelsim prompt or .do file:
restart -f;
vsim test_mydesign;
add wave *;
run;

If you're starting Modelsim from the ISE process view (e.g.
double click on "Simulate Behavioral Model") you are actually
starting Modelsim with a script that loads the design, compiles
it and runs the simulation (default for 1 microsecond, but this
is configurable in the ISE properties).
When you change a file inside ISE, make sure it is saved and
then rerun the script in modelsim. I find the easiest way to
rerun the script is to click on the right pane of the main
Modelsim window and then use the up-arrow key to get
back the line that ran the script (something like "do
testbenchname.fdo")
This basically does the same thing as closing and re-running from
inside ISE, but without the added time of re-loading Modelsim. It
also preserves your simulation options (like default radix and run
time),
but you'll need to save your waveform view between runs if you've
mad a custom signal list in the wave window. |
