New White Paper: Routing Congestion De-Mystified

Comments(0)Filed under: Synthesis, RTL compiler, logic desgin, white paper, congestion, routing

Even though routing congestion sounds like a physical design problem, it can cause chip projects to miss schedules, miss performance targets, or result in a larger die size.  These are problems that are shared across the project, so if you want to control the success of your chip design project, it is something to be concerned about.  But still, what can a logic designer do about it?

Fortunately, today's physically-aware synthesis tools like RTL Compiler can help relieve many congestion issues before they even show up in physical design.  More importantly, you can use this technology to identify congestion issues up-front and quickly triage the source of the problem.  Maybe it is something that can be fixed during synthesis, or maybe it is a floorplan issue that the physical design team needs to address.  There are no "magic bullets" because the nature of the problem is so complex, but you can identify that there is an issue up-front and figure out an action plan to address it before it affects the project schedule's critical path.

Taking advantage of this requires some amount of understanding of the types of problems that can occur, as well as methods for addressing them.  Fortunately, some of our leading synthesis experts that are well-versed in physical design issues - Matt Rardon, Ankush Sood, Mike Clarke, and Diego Hammerschlag - have put together a nice white paper, Eliminating Routing Congestion Issues in Synthesis, that explains the issues and solutions as they apply to logic design and synthesis.  Even a synthesis marketing guy could understand it!
