WebJul 3, 2015 · 1 Answer. Sorted by: 2. Keep a vector of 130 bits, and use it as a shift register. As you have to load at least 130 bits until you begin to process header and data, keep searching for the header at positions 128 and 129 of that vector (the two leftmost bit positions). When the header is detected, the next 128 bits already loaded in your 130 bit ... WebVariable slicing vector Systemverilog. Ask Question Asked 4 years, 2 months ago. Modified 4 years, ...
