Physical Design (PnR)

Neural Semiconductor offers Physical Design services as one of the turnkey services covering Constraint Analysis, Synthesis, Flow Development, Physical Design Implementation, Formal Verification, Physical Verification (LVS, DRC, Antenna), Power Analysis, Static Timing Analysis (STA) and signoff. We’ve passionate backend engineers trained with industry standard tool flow.

We experiment multiple scenarios before meeting the constraints with frequent Logic Equivalency Check (LEC) after the Synthesis flow and PD implementation through Floorplan, Power Analysis, Placement, Clock Tree Synthesis (CTS), Routing etc.
