1.0.1 System Generator for DSP - "Error reported by S-function 'xlfir' in block I_InterpolateBy2_CoeffWithDecimals"

Description

Keywords: System Generator, SysGen, MathWorks, Simulink, Matlab, FIR

Urgency: Standard

General Description:
I've loaded and installed the V1.01 and the update, and Simulink can now see the poly-phase FIRs. However, I encounter this error message:

"Error reported by S-function 'xlfir' in block 'pred_tb/PDP_FPGA/InterpolateBy2/I_InterpolateBy2_CoeffWithDecimals'"

Solution

When using the interpolated FIR, ensure the output sample period is an integer. (This means that the input sample period has to be a multiple of 2 for an 1:2 interpolator.)
