3.1i Virtex-II MAP - ERROR:Pack:269 - Invalid "CLKDV_DIVIDE" property of '<n>' found on CLKDLL symbol.

Description

Keywords: DLL, CLKDLL, CLKDV_DIVIDE, CLKDV, ERROR:Pack:269

Urgency: Standard

General Description:
When I specify the DLL divisor value for a Virtex-E, the following error occurs in MAP:

ERROR:Pack:269 - Invalid "CLKDV_DIVIDE" property value of '<n>' found on CLKDLL
symbol. The only accepted values for "CLKDV_DIVIDE" are 1.5, 2, 2.5, 3, 4, 5, 8 and 16.
ERROR:Ncd - Primitive "DIVIDE_ATTR" can not be programmed with "DIVIDE_ATTR:
1075576832" in "DLL". Syntax Error. The setting "1075576832" is not a valid for
"DIVIDE_ATTR".

FATAL_ERROR:Pack:pksvrclkdll.c:176:1.4.18.2 - Problem configuring CC.

Solution

First, be certain that a valid CLKDV_DIVIDE value has been specified. If so, then the problem can be worked around by setting the variable "XIL_<site>_DIVIDE_BY", which will force BitGen to override the CLKDV_DIVIDE value when the bitstream is generated.

For example:

set XIL_DLL2P_DIVIDE_BY=7 (PCs)
setenv XIL_DLL2P_DIVIDE_BY 7 (Workstations)

This problem will be fixed in the 4.1i release, which is currently scheduled for September, 2001.
