Tech Tip: DDR Byte Lane Matching Strobe
DDR designs require a DDR byte lane and strobe signal match. Sometimes, it is also necessary to have multiple byte lanes and strobes matching together. There may be many byte lanes in the design. Balancing and optimizing trace lengths for multiple DDR byte lanes and strobes will be a challenge.
CR-8000 Design Force provides the solution for this challenge. It allows for nested skew group settings and utilizes the routing tools for optimized constraint-driven Lengthening.
This video shows how to set up the skew group for a single byte lane as well as multiple byte lanes together in CR-8000 Design Force. It also shows how to use its “Lengthen” function to match the PCB trace length at once.
