| 步骤： 像运行DRC一样地先执行LVL1.COM , 注意，产生的DAT文件不要杀掉，然后在同一个文件夹下再运行LVL2.COM， 然后在VIRTUOSO里做查看DRC ERROR一样查看2个LAYOUT的相异之处。 OPENBOOK里有例子。关键的几个命令字就是：EXPORT , IMPORT-LAYER , 和XOR。 ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ LVL1.COM 内容如下： *DESCRIPTION INDISK = old.gds PRIMARY = tapeout top cell name SYSTEM = GDS2 cad graphic system OUTLIB = old OUTDISK = old.out KEEPDATA = YES *END *INPUT-LAYER PPWELL = 1 NNWELL = 2 EXPORT PPWELL EXPORT NNWELL *END ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ LVL2.COM 内容如下： *DESCRIPTION INDISK = new.gds PRIMARY = tapeout top cell name PRINTFILE = comp OUTLIB = compout OUTDISK = comp.out KEEPDATA = YES *END *INPUT-LAYER PPWELLB = 1 NNWELLB = 2 IMPORT-LAYER PPWELL IMPORT-LAYER NNWELL *END *OPERATION XOR PPWELL PPWELLB ERR0 OUTPUT PWELL 1 XOR NNWELL NNWELLB ERR1 OUTPUT NWELL 2 *END ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ |
