10.1 ChipScope - DRC fails for ChipScope ILA when using C_NUM_DATA_SAMPLES higher than 16384 for Virtex-5 devices


When I attempt to use C_NUM_DATA_SAMPLES greater than 16384 for Virtex-5 FPGA for ChipScope ILA, the following error message occurs:

"Running DRC Tcl procedures for OPTION IPLEVEL_DRC_PROC...

ERROR:MDT - chipscope_ila_0 (chipscope_ila) - Invalid value : 131072 for


Valid values are : 512 1024 2048 4096 8192 16384.

while executing

"error "Invalid value : $params(C_NUM_DATA_SAMPLES) for Parameter


Valid values are : $data_sample_range.""

(procedure "::hw_chipscope_ila_v1_02_a::ila_drc" line 67)

invoked from within

"::hw_chipscope_ila_v1_02_a::ila_drc 58309464"

make: *** [implementation/download.bit] Error 1



This error occurs because the default value is taken for the device and the Virtex-5 device is not recognized in the TCL script.

To work around this problem, modify the TCL script in the EDK pcores directory:


Add the following values to line 351: 32768 65536 131072

This issue has been fixed in EDK 11.1.
