Hello. Thanks for the awesome program, it really helps to understand the basics! I have a question with my 8bit reverse(bidirectional shift) register. I need to build it on RS flip flops and i get some troubles with different behavior of my own made RS and the library's one. I attached a file of my project, there are 2 main schemes, main and "main with native RS" and they are work different when it needs to shift loaded data in register. Native RS flipflop do it perfectly and mine doesnt work at all. I want to ask, how can i get the inside scheme of yours RS and compare with my to solve that problem. Thanks.
