2.1i COREGEN, C_IP4: "Illegal value FALSE for variable write_mif" when regenerating Coregen RAM for Virtex

描述

Keywords: illegal, block, ram, virtex, false, c_ip4, coregen, dual, single, port, distributed,
memory

Urgency: standard

General Description:
When trying to regenerate the Dual Port and Single Port Block RAMs or Distributed
Memories by reading in an XCO file generated using an earlier IP update release
(C_IP2, C_IP3), the following error may appear in a popup:

"Illegal value FALSE for variable write_mif"

解决方案

In the C_IP4 version of the Dual Port and Single Port Block RAMs and Distributed
Memories, the WRITE_MIF option must be set to "True" so that the MIF file is always
written out by the core.

Edit the .XCO file and change the value of the WRITE_MIF option from
"false" to "true", then regenerate the core by reading in the modified
.XCO.
