功能仿真没有错误（包括不加sdc的网表文件仿真），TimeQuest没有报错，但是时序仿真时，ModelSim报了hold错误，并在报错时间后面一点，大部分信号就变红无效了。下面是报错信息：
# ** Error: e:/altera/80/quartus/eda/sim_lib/cycloneii_atoms.v(5287): $hold( posedge clk &&& nosloadsclr:255510282 ps, datain:255510283 ps, 266 ps );

# Time: 255510496 ps Iteration: 0 Instance: /tb/inst/\arm9_core_inst|arm9_compatiable_code_inst|cmd[0]\
请各位大神指点指点

已解决
请问怎么解决的?
哎，不给个说法，是不是仿真的频率太高，信号hold slack不足问题，我现在遇到类似情况，想确认一下
