你看看端口相应的金属Text用对没有。
我的GDS是ICC生成的,ICC里看都有port。
spi网表是verlilog网表生成的。对比的是gds和spi网表。
text我不知道怎么看,第一次做后端,也没怎么学过
不是有设置write_stream mode的命令吗?-output {geometry text}?具体给忘了,查查吧
应该是你在输出数据是没有打Label
请问label怎么打呢?
我现在输出gds的指令是:
set_write_stream_options -reset
set_write_stream_options -map_layer gdsout_6X2Z.map -child_depth 99 -flatten_via -keep_data_type\
-output_pin {text geometry} -output_net text -output_polygon_pin
write_stream -format gds -lib_name TOP_LIB -cells top ./output/top.gds
谢谢各位
我打上TEXT后就port了,现在lvs是incorrect,net和 instance数目不对。
ICC 到virtuoso的数据,需要确认
1,stream map文件是否正确,用到的层是否能对上
2,ICC吐数据出来的时候depth要设置的足够深,否则吐gds出来的时候port name也出不来的
