Anyone have experience on the performance comparation of timing closure, physical implementation flow:
1, JupiterXT floor plan + physical compiler placement + Astro route
2, netlist -> Jupiter floor plan + Astro timing driven plance and route
3, netlist -> SOC encounter floor plan, timing driven place, nanoroute
I tried a small block 270um X 270um register dominate block. physical compiler, JupiterXT/Astro took a lot of time to fix the negate slack. While encounter is much fast and got timing closure. Did I miss some thing in encounter or encounter is just better?
