SE载入DEF时系统提示
##-I File place_fifo.def line 121
##-I ( 260 260 ) + RECT metal1 ( -380 -280 ) ( 380 280 ) ; <<<<
** EXCHANGEFORMATS-USER-162 WARNING **
Via V12_H is ignored because it already exists in DB
我不理这些warning,继续做,完成之后,输出verilog时出现一堆类似下面的错误:
** SE-USER-61 ERROR **
14:45:47 * pbodiff : Instance dout_reg refers to two different cells: FFSJKRHD4X and FFSJKRHD1X
** CADENCE-USER-53 WARNING **
Input source will abort at next read due to limit of 1 PROBLEMs.
把我的流程写在下边,请指正:
执行se.ini
载入foundry提供的lef
载入foundry提供的gcf(存档命名为library)
载入综合后产生的verilog代码
floorplan
place io
plan power
place cell
compact floorplan
clock tree generation(存档命名为place_design)
重新载入library(就是刚才存过的)
载入save后产生的place_design.def
connect ring
add filling cell
clock route
wroute
report sdf
export verilog,def
