Observing CPLD pins

Hi, Is there a tool to observe pin states of a running CPLD? SignalTap works only with FPGA devices. Thanks.

The only limitation with JTAG tools is, since they serially load data in and out, they can't keep up with most "live" clock rates ...

The distinguish feature of Scanseer in comparing to another well known Universal Scan tool is speed. Scanseer is much faster. Its sampling rate is about 1000 captures per second when working through Amontec JTAGkey cable. UniversalScan always samples a chain at about 10Hz rate.
