I have a design that contains many FIR
filters, each one of them having its own different coefficient sets. I
use the MAC FIR v5.1 core to generate the filters, but, according to AR #16433,
if there are many MAC FIR cores, they should be placed in subfloders,
because otherwise the .mif files will be overwritten. I did that, but
now there is another problem: According to AR #24807,
ISE 9.1 does not allow to add IP cores from remote directories and the
workaround to this solution is to copy the IP core to a different
directory from the project directory, and then use the "Add Copy of
Source..." option to add the IP core. However, such an action would
eventually copy all my MAC FIR IP cores to the project directory, which
contradicts the suggested workaround from AR #16433, since the .mif
files will be overwritten! Not to mention that according to AR #24477,
some of the IP cores files must be manually copied to the project
directory, since the "Add Cop of source..." fails to copy all the
required IP core files generated.
I hope that I have
written in a clear way my problem. Unfortunately I cannot use a
different version of ISE. Furthermore, as I said to a previous thread,
there are other problems when using the FIR Compiler Core generator,
that's why I swtiched to the MAC FIR Core.
Any suggestions would be great.
