Your post appears to be more about PCB, ASIC, or FPGA. One of the posts appears to be dealing with placement and routing congestion. Your other question appears to be about clock distribution. Neither of these questions are appropriate for the Elementary Electronics section. The answer for dealing with or solving clock delay/latency and GRC are different depending on which forum the question should have been posted in.
You should not expect volunteers (we aren't paid to answer questions) to perform google searches for you and copy the results onto edaboard. Thi is not an effective method for getting timely answers. Usually doing this results in negative feedback until the question/answer cycle damps to 0 replies. The more detailed the question and the more effort you show in attempting to answer your question yourself will get more favorable responses.
