更进一步了解问题之后,现在的问题描述如下:
when i use FPGA to do verification about ASIC's gated clock, this issues (clock gating) occurred , i use synplify_perimer_dp to synthesis ,
when i set "Fix Gated Clocks" as '0' the geted cell logic was existed exactly , but when i set "Fix Gated Clocks" as '3'
my geted cell module was removed,by waring:
"Removing sequential instance X of view:X because there are no references to its outputs "
I have checked all outputs from the module ,all of them are connected correctly
somebody help me ,thans a lot ... |
