[casper] about complex FFT core problem

Hello, I have tried to the complex FFT core . During the simulation,the system generator give out the error as below: Slice endpoints must lie between the LSB and MSB Error occurred during Rate and Type Error Checking. Maybe the input now is not correct,because I have connect the real_pfb's

Re: [casper] about complex FFT core problem

Hi Wang This error occurs when you have a data bus and are trying to use part of it that does not exist. This means that a Slice block is expecting a wider data bus than your design is giving it. For the FFT it may be that the shift input does not have the correct width, or possibly your data
