ERC检查语法

提示：很多名次是要定义的，需要结合layout的情况，进行定义。

---

一、高压和低压直接相连的情况

ATH CHECKING
{@……
THICK_NSD = (NSD AND HGO) NOT ESD
THICK_PSD = (PSD AND HGO) NOT ESD
THIN_F_POLY = ((POLY NOT INTERACT RPOLY_ALL) NOT HGO) NOT ESD
NET AREA RATID THIN_F_POLY THICK_NSD > 0
NET AREA RATID THIN_F_POLY THICK_PSD > 0 //net area ratid 这个是相交面积的固定语法
}

二、电源和地是否连接错了

//	well and sub bias check	//
{@PTAP CONNECTS TO POER
	NET PTAP LVS_POWER_NAME	//NET A B
}

三、浮空的栅极

//	floating gate
{@……
A = (POLY INTERACT GATE_ALL) NOT INTERACT (CONT AND M1)
B = ((GATE_ALL INTERACT A) OR (POLY INTERACT (GATE_ALL INTERACT A))) INTERACT (CONT AND M1)
A NOT B
}

四、浮空的阱

//	Floating well
{@ there is no power or ground node information connecting to well or sub
A1 = NET NDTE LVS_POWER_NAME
NDTE NOT A1
B1 = NET NWE LVS_POWER_NAME
NWE NOT B1
C1......
}

五、浮空的有源区

//	floating diff
{@floating diffsion no any cont
NTAP NOT INTERACT (CONTA AND M1)
PTAP NOT INTERACT (CONT AND M1)
}

六、浮空的孔

//	floating contact
{@……
CONT NOT INTERACT (DIFF OR POLY)
}

七、浮空的金属

//	floatingmetal
{@……
M2 NOT INTERACT VIA1//这里是TM2的情况，如果是TM3、TM3以此类推。
M1 NOT INTERACT (VIA1 OR CONT)
}
