To overcome this, I implemented a systematic approach that combined automated and manual ECOs to improve block-level timing. I managed the entire flow from synthesis to placement and routing of these blocks, ensuring they synchronized properly with other chip components. We faced numerous LVS and DRC violations that threatened our timeline, but I came up with elegant solutions to fix them while still meeting the stringent timing and power requirements of the chip. I developed custom routing strategies for critical IPs and coordinated extensively with timing and DFT teams to ensure cohesive solutions. By setting up comprehensive regressions and test blocks, we were able to refine our PNR flow iteratively. This methodical approach not only resolved our immediate challenges but also established best practices that enhanced efficiency for future designs.
