How to manually layout shift registers

[tia_design]

In my design, I have a 16-bit shift register. I simulated it in schematic, and there is no setup/hold time violation. But I don't know what is good strategy to do its layout to avoid any potential setup/hold time violation. Should I put each register as close as possible? Shoud I put buffer between each register. Thanks a lot!

For shift register design, setup time isn't a problem. And hold time is more important to pay attention on it. To avoid feedthru problem, it's better to insert some small delay between each register when you design it manually.

Hope it helps
