      HI,

      I use the S27KS0641's model emulate the controller,but Modelsim hint "Error: C:/Users/Bruce/Desktop/Psram_Interface/s27ks0641.v(375): $skew( negedge CSNeg:41697163 ps, posedge CSNeg:42007173 ps, 1 ps );".The ck is 100MHz,and only Write 32 bytes,we have provided 12 cycles of latency. There is only 310ns from the negedge of CS to the posedge of CS.What the error tell us?Thank you.2020-08-19_210119.png
