"ERROR: tRFC maximum violation during No Op" occur in modelsim simulation!
In my project, i add a DDR2 HPCII and some other avalon master in SOPC system. when simulation in modelsim, error "tRFC maximum violation during No Op" occur in modelsim simulation!" occured after running a certain time. and then simulation is paused.
I have checked the parameter set for the DDR2 HPCII. and the tRFC is set to 105 ns. it's the same as the parameter set in ddr2_parameter.vh, which is as follow: parameter TRFC_MIN = 105000; parameter TRFC_MAX =70000000; need help!
