Hi. I have a problem designing a handshake sistem. I think it's imposible to do it to the tasks. I must have two different clocks. For instance ck1 with a period of 7 and clock 2 with a period of 5. ...

There are a few ways to do what you need, but this depends on some unspecified details; for example: - where ck1 and ck2 come from? (external? generated from fpga?) - is there a fixed phase relation between them - what can you change and what not In the worst case where ck1 and ck2 run independently and you don't have a higher frequency clock, your signals would necessarily suffer a time uncertaintly up to the maximum among ck1 and ck2 period. This is unavoidable. You can reduce it to half by sampling on both edges, but I would not recommend this.
