我是在synplify中设置的多周期约束,没有设置路径(是从dvsor到n1的多周期约束)。在designer编译中出现如下错误
Error: in Constraint checker: Invalid multicycle constraint - the -to object list "\1I220/N_1[11]:D" is incorrect.
From: \1I220/dvsor_1[1]:CLK
Through: N/A
To: \1I220/N_1[11]:D
Constraint origin: D:/Actelprj/controller/synthesis/ally_sdc.sdc, line 509
问下这个是怎么回事?该怎么弄才能好呢?
