1. Clearance Constraint (Gap=10mil) (All),(All) 间隙约束,也就是约束PCB中的电气间距,比如阻容各类元件的焊盘间距小于规则中的设定值,即报警。 规则设置如下图: 如上图的表中,可以分别设置走线(Track)、贴片焊盘(SMD Pad)、通孔焊盘(TH Pad)、过孔(Via)、覆铜(Copper)、丝印字符(Text)、孔(Hole),...
如果IP有多个电压,建议在net上识别为最高电压(highest voltage text or marker layer)。 如果net上没有任何voltage high text/marker layer,同时连接到PW strap,则voltage high会被识别为0V。 如果net没有任何识别信息,DRC将会检查这条net是否连接MOS/HV Diode器件,如果没有连接,则voltage high会被识别为0V;如果...

Step 5. Once the sub-blocks are exhausted, we do the error types (from ERR_list) in the 'subcell_list'. For each error type, we parse the ERC_COMB.db to sense the check name, followed by the error markers until it hits the next check in the database. In this phase, we create...
