Urgency: Standard

General Description:

Is the routing used for the TAP pins visible in XDE or EPIC?



Solution 1:

When the TDI, TMS, TCK and TDO pins are used for Boundary Scan
in the XC4000 and XC5200 families, the routing is not visible
in either XDE or EPIC.

There is no way of routing these pins via XDE or EPIC.
