各位大侠,我在用encounter做optDesign -preCTS时总是跑不下去退出我的命令是
setOptMode -fixCap true -fixTran true -fixFanoutLoad false
optDesign -preCTS
出现的错误如下
*** Starting refinePlace (0:31:52 mem=3237.4M) ***
default core: bins with density >0.75 = 45.8 % ( 7444 / 16240 )
RPlace IncrNP: Rollback Lev = -3
RPlace: Density =1.157778, incremental np is triggered.
Checking spec file integrity...
Clock gating cells determined by native netlist tracing.
**ERROR: (ENCSYUTIL-15): Cannot malloc type "npsBin" size=268435456 bytes.
Probably ran out of virtual memory.
请大侠们帮忙分析一下是设计本身的问题还是真的虚拟内存不够造成的?
多谢!

估计是内存不够
那我该怎么办呢?在place这一步时序不满足的话,该怎么优化?
物理内存不够的话,换机器
足够的话,用64bit encounter
需要重新换机器,之前安装时也出现内存不够用的问题
