Automated IR convergence with PrimeClosure IR-ECO
DescriptionIn this work, a workflow of automated IR violation fixing based on Synopsys PrimeClosure IR-ECO is presented, which tries to address the "last-mile" IR convergence issue while minimizing manual effort from design engineers.
Redhawk-SC IR signoff tool analyzes the aggressor cells in layout and calculates IR-drop violations and information, which is then fed to PrimeClosure.
PrimeClosure IR-ECO can automatically identify the correct fixing by cell swapping, sizing or moving, while being timing and DRC aware.
The cell change list from PrimeClosure can be passed to PNR construction tool to apply design changes, while can be also annotated back to Redhawk-SC to get updated IR-drop results for the fixed cells.
Experiment data from test blocks in advanced process node indicates that the proposed automated IR-ECO flow can achieve satisfactory IR violation reduction while being timing and DRC friendly.
Along with the "shift-left" early in-design IR analysis, as well as timing aware IR signoff analysis, the three components complete an end-to-end IR convergence flow which can boost the execution efficiency for physical design teams.
