10.1 ChipScope Pro - "ERROR:Xst:1617 - Processing TIMESPEC TS_U_TO_D: user TIMEGRP 'D_CLK' must be previously defined in FROM/TO constraint."

Description

Keywords: MDM, BSCAN, JTAG, xmd, logic, Analyzer, ATC2, ICON, ILA

The following errors occur when I use an EDK design as a submodule in ISE, while debuggind the ISE portion with ChipScope. If you include the ICON core in the EDK portion to automatically hook up the JTAG pins, then synthesis errors out because the NCF is included and it cannot find D_CLK.

"ERROR:Xst:1617 - Processing TIMESPEC TS_U_TO_D: user TIMEGRP 'D_CLK' must be previously defined in FROM/TO constraint."
"ERROR:Xst:1489 - Constraint annotation failed."

Solution

To work around this issue:

1. make a local pcore for chipscope_icon_v1_02_a
2. uncomment the line below in the TCL file (line 192):
exec rm -f [file nativename[pwd]]/implementation/$params(INSTANCE)_wrapper/$params(INSTANCE).ncf

This issue is resolved ChipScope Pro 11.1.
