Boundary Scan/JTAG: How to co-relate the states in the XC9500 SVF files
to TAP controller states?



Problem Description:
Keywords: tap, svf, xc9500, 9k, 9500, controller, states

Urgency: standard

General Description:

The XC9500 SVF files seem to be using different names as compared
with the TAP controller FSM. How to co-relate those?


Solution 1:

The following is a list of SVF state names used for each IEEE
1149.1 TAP state name.

IEEE 1149.1 TAP state name     SVF TAP state name

Test-Logic-Reset	       RESET
Run-Test/Idle		       IDLE
Select-DR-Scan		       DRSELECT
