quartus编译产生如下警告:
Warning (10227): Verilog HDL Port Declaration warning at SHA.v(10): data type declaration for "HASH_OUT" declares packed dimensions but the port declaration declaration does not
Warning: Found 32 output pins without output pin load capacitance assignment
Warning: Found 32 output pins without output pin load capacitance assignment
按照quartus中提供的help 给出的解决办法:
use the Assignment Editor (Assignments menu) to specify a value for the Output Pin Load logic option
结果waring还是没有消失。然后用quartus中的timequest timing analysis进行时序分析,里面显示:
property steup hold
Unconstrained Output Ports 32 32
Unconstrained Output Port Paths 32 32
找了很多资料还是没解决,所里写上来问问大家有没有碰到过同样的问题,帮忙解决一下。谢谢!
