Hello, For my Simulink code, I am attempting to pad my input data with zeroes. The format should be as follows:
0000000data0000000data...
However, the data is not taken in by frame, and I cannot convert it since I want to use HDL generation. How is this achieved?

you may want to try using bitconcat function supported by HDLCoder.
z = fi(0, 0,7,0); % create 7-bit zero word
y = bitconcat(z,u,z) % u in the input word in fixed-point format

If your input data is a frame, you can pad zeros and then use the To Sample block for the HDL input.
If you are dealing with samples, I suggest using a counter block followed by a switch block. When the counter is < specified length, pass in zeroes, otherwise send in the data.
