Hi,
I am using SignalTap (9.1) to debug my design. When I have about 100 signals, everything works as expected. However, when I use much more signals, let's say 200, the behavior get's incorrect: The data is obviously incorrect (i.e. more or less complete non-sense while the design is still working like before), and/or the triggering fails, even the time-scale is incorrect (e.g. from 0 to 3072 instead of -1024 to 3072, or -2048 to 2048, althought "Pre trigger-position" is selected).
Other settings (beside signal-number) like sample depth appear to have no influence.
Has anyone observed the same behavior, or is this something specific to my design / system?
Thanks,
Thomas

Hi,
did you get timing violation for the signaltap part of your design ?
Kind regards
