Honored ContributorXilinx ChipScope has Virtual IO core, which can monitor and drive internal FPGA signals.
Here is its spec (http://www.xilinx.com/support/documentation/ip_documentation/chipscope_vio.pdf). I wonder if Altera tools have something similar. I was unsuccessfully trying to find in SignalTap documentation. Thanks, Evgeni
Honored Contributorsources and probes. there is a megafunction
Honored ContributorSource and probe offers part of the functionality: Drive signals quasi-statically, not changing at design speed.
A real time stimulus generator would be an interesting extension to SignalTap, but isn't yet available from Altera. For the time being, you need to design similar test tools yourself. You can e.g. download stimuli to a block RAM through the memory editor tool and replay it by a simple state machine. The SignalTap trigger out feature can be used to synchronize a stimulus generator.Honored ContributorWhich type of RAM is most suitable for this purpose?
Honored ContributorThanks for all your responses.
