Introduction - If you have any usage issues, please Google them yourself
Please design a 4 bit shift register, requirements are as follows:
1) asynchronous reset
2) synchronous loading
3) to complete the shift left, right. The displacement mode can support the arithmetic, logical, and cyclic displacement.
4) to complete the simulation, prove the function correctly.
5) can see the comprehensive results.
Note: do not need a bit input, parallel output load can also use the parallel output.
