FIR Compiler 7.1 in Vivado Sysgen gives the below error when "Hardware_Oversampling_Rate" is selected in the "Select Format" of "Channel Specification" tab.
The following errors occured with the FIR_test1/FIR Compiler 7.1 block: 1. ERROR: Validation failed on parameter 'ColumnConfiguration(ColumnConfig)' for The sum of the Column lengths (2) does not match the required number of DSP48s(3) 2. .BD Cell 'fir_compiler_7_1_03df0914cb'
This is a known issue.
You can work around this problem by changing the "Select Format" option to "Maximum_Possible", click Apply, then change back to "Hardware_Oversampling_Rate" and the error does not re-occur.
