Timing Constraints​

In a SOC world now dominated by low power and massive functionality, it takes many clocks in a design to achieve the desired platform.  Once a couple of clocks were all you needed and now you may have several hundreds of clocks for a design.  Key fundamentals to proper synthesis (not over optimized) is a good timing setup.  This then holds true for physical design as well.  


Achieving those goals is what Sintegra really understands. Working with Static timing tools and driving a good synthesis result and especially using topology-based when available provides a low power design that meets the timing requirements.  Here are some key items Sintegra will help with:

  • Create proper io timing for block partitioning (60/40 starting point then refine)

  • Identifying Multi-cycle or false paths

  • Use of multi-mode and multi-scenario to help define the design

  • Identifying High Fanout Logic

  • Specifying clock latency numbers to balance timing

  • Use of multi clocks through single inputs

  • Signal Integrity setup and checking

  • Latency balancing between io and internal logic

  • Designing to meet advanced rule checks (clock trans vs std cells)
