DRC一直有这样的错误
LUP.6g { @ Any point inside NMOS source/drain space to the nearest PW STRAP in the same PW <= ^LUP_6g um
@ Any point inside PMOS source/drain space to the nearest NW STRAP in the same NW <= ^LUP_6g um
@ In SRAM bit cell region, the rule is relaxed to ^LUP_6g_SRAM um
PACT_CHECK_NON_SRAM NOT NSTP_OS
PACT_CHECK_SRAM NOT (NSTP_OS OR NSTP_OS_SRAM)
NACT_CHECK_NON_SRAM NOT PSTP_OS
NACT_CHECK_SRAM NOT (PSTP_OS OR PSTP_OS_SRAM)
}
连single transistor也会有。。 让我纳闷
除了改DRC规则成这样,实在无头绪:
// PACT_CHECK_NON_SRAM NOT NSTP_OS
// NACT_CHECK_NON_SRAM NOT PSTP_OS
@ Any point inside NMOS source/drain space to the nearest PW STRAP in the same PW <= ^LUP_6g um
@ Any point inside PMOS source/drain space to the nearest NW STRAP in the same NW <= ^LUP_6g um
这不是说的很清楚了,mos离sub的距离 不能大于 LUP_6g 这个值了,你查查drc command file里面,定义 LUP_6g这个值是多少?
