12 years ago --- Quote Start --- If you have a signal incrementing every 100 clocks, and you need to capture the counter going from 0-32, you need a 3200 sample window minimum. Have you simulated the design before you compiled it? signaltap is a debug tool, not a verification tool. --- Quote End --- I have a 50 MHz input clock which is assigned to the crystal on the DE0-Nano board. I am using this then in the serial configuration section on the right in SignalTap as the clock. I have divided this clock by 512 in my code and and when a button is pressed, a counter starts to count from 0 to 32 on every positive edge of this clock pulse. I have put this counter in the start and stop storage qualifier from 0 to 32 and when I press the button, I have no idea why it wont show me the counter from 0 to 32 and all the other signals. I have tested this code on the development board with LEDs etc. and all works fine but I am unable to simply view the signals on SignalTap. What else could I be doing wrong? I have selected 8K as the sample depth also. Thanks
