14 years ago --- Quote Start --- Which DMA are You using? SGDMA has way much better results than simple DMA. Nios systems running above 100MHz needs to be timing constrained very well. --- Quote End --- I am using DMA. SGDMA is hard to understand, i am still struggling with it, do you have a simple example involving SGDMA? like transferring ST to memory or memory to memory? What if i do not do any timing constraint on NIOS2? what will happen? I thought the .sdc file is generated by SOPC builder automatically after HDL is generated? so all i have to do is just include the cpu.sdc into the timequest timing analysis? Michael
