The contents of the frame data passed into the TEMAC receiver can be changed by editing the DATA fields for each frame defined in the test bench. The test bench automatically calculates the new FCS field to pass into the TEMAC, as well as calculating the new expected FCS value. Further frames can be added by defining a new frame of data.
If frame filter is enabled, the first 4 frames have the same DA and SA data matching the value of what the frame filter is set to. The fifth frame is dropped because by default it has different DA/SA data than the first 4.
In the example design the address filter is set to:
DA = 48'h0605040302DA
SA = 48'h06050403025A
If none of the frames has this DA/SA setup, all frames are dropped by the address filter.
address_filter_value parameter has no control over the value
the address filter is set to.
