2013.4 FIR Compiler v7.0/v7.1- When a COE file is used to specify filter coefficient on an IPI instance of the core, the bus properties will be incorrect and potential TCL errors generated

Description

When a COE file is used to specify the filter coefficient on an IPI instance of the core, the bus properties will be incorrect and a TCL error may be generated (depending on the number of coefficients sets that are specified).

Solution

This is known issue with v7.0 and 7.1 release of the FIR Compiler with Vivado Design Suite 2013.4.

To work around this problem, use the CoefficientVector parameter to specify the coefficients directly in a GUI/User parameter. You might need to specify the CoefficientVector in decimal format.
