7.1i Schematic - The error " '0000..1000000' is not a legal value for 'INIT_01' " displays when you initialize a block RAM using the schematic GUI

Description

Keywords: GUI, initialization, initialize

When using the schematic editor to initialize a block RAM (e.g., ramb16_s1), I receive the following the error:

"'0000..1000000' is not a legal value for 'INIT_01' attribute"

Solution

The initialization check for block RAM components is not setup correctly in the 7.xi schematic capture libraries.

To work around this issue using 7.xi ISE design tools, initialize the block RAM values in a user constraints file (UCF).

This issue has been corrected in the 8.1i ISE release.
