Ddr length matching
WebPackage delays for DDR3 length matching Can I assume an average propagation speed for all signals in a BGA package from the die to the balls? The reason I'm asking is I would like to convert the package delays (in time) to some "trace length" then add that to my CAD software (Altium) to length-match those signals. WebAs per UG583, we have length matched the address and clock lines from FPGA to each DDR4 device. However, we see that overall length of address and clock lines are not …

WebAug 13, 2024 · PCB trace length matching is crucial for high frequency synchronous signals. As you’re probably aware, signals travel on PCB traces with a certain speed. … WebIn UG933 it is recommended that consider package delay of chips in DDR length matching. I already exported package delay of the ZYNQ chip from Vivado and compensate FPGA package delay in Allegro (My layout software). My question is do I need to look for the delay in DDR chip too? My chosen DDR chip is a 8Gb Micron DDR3 with 96FBGA package.
WebJun 14, 2007 · Well, DDR signals are high-speed and they have to meet the specific speed requirements and that's why they have to be very closely matched and not to exceed the timing margins. The matching rules depend on the DDR type and the memory arrangement as well as the controller interface type.
