yangsy85

在后端区发的帖沉了，转这里请教高手 小弟正在尝试calibre LVS+QRC的提参流程，工艺是SMIC 28nm PS，遇到以下两方面问题，求给建议 软件及环境： 1）Redhead 5 2）Cadence IC 6.1 3）Cadence Extraction QRC - Parasitic Extractor - Version 10.1.3-p065 （安装文件用的http://bbs.eetop.cn/thread-355374-1-1.html，patch将就用的IUS 9.2http://bbs.eetop.cn/thread-268069-1-1.html） 4）calibre 2013.3_39.24 一、virtuoso layout XL无法加载QRC UI 按网上说明，在cdsinit文件加入配置，但layout工具栏上仍然看不到QRC的调用按钮。 二、使用命令运行QRC，生成capfile时报错 报错信息 WARNING (LBMISC-215001): file 'via1' is not a flat edge file ERROR (LBMISC-215002): it is a hierarchical edge file 做LVS时已选择Flatten QRC命令行流程： 1. run lvs by GUI with lvs.cmd (fab provided), and make a clean result 2. run lvs by GUI with xrc.cmd (edited from lvs.cmd according to fab‘s guidance). 3. run calibre：calibre -query_input query_cmd -query svdb xrc_test 4. run：qrc -cmd qrc_cmd qrc_cmd file： output_setup -temporary_directory_name qrc_output log_file -file_name qrc_output/qrc.log process_technology -technology_library_file "qrc_rule/QRC_28PS_1P8M_6Ic_2TMc_ALPA1_V0.5_1T/rulefiles/tech.lib" -technology_name CMAX input_db -type calibre -directory_name query_output -run_name Design -layer_map_file query_output/Design.gds.map -device_property_value 7 -instance_property_value 6 -net_property_value 5 -library_cell_list_file qrc_rule/assura_QRC/preserveCellList.txt -hierarchy_delimiter \/ -design_cell_name test_qrc av_extracted test_qrc output_db -type dspf qrc.log file： （前面运行内容省略） #==========================================================# # Run pax16 to generate capfile #==========================================================# pax16 -V -scf sip.cmd -M_perim_off -cgnd ${CAP_GROUND},1.0 -c \ /home/yangsy/tmp/28qrc/xrc_test/qrc_rule/QRC_28PS_1P8M_6Ic_2TMc_ALPA1_V0.5_1T/rulefiles/CMAX/qrcTechFile \ -f FOXA active poly metal1 metal2 metal3 metal4 metal5 metal6 metal7 \ metal8 alpa_inter - \ /home/yangsy/tmp/28qrc/xrc_test/qrc_rule/QRC_28PS_1P8M_6Ic_2TMc_ALPA1_V0.5_1T/rulefiles/CMAX/qrcTechFile \ - - NET - capfile rdpaxcmd took 0.35 user, 0.15 sys, 1.00 elapsed, 47952.0 kbytes WARNING (LBMISC-215001): file 'via1' is not a flat edge file ERROR (LBMISC-215002): it is a hierarchical edge file ERROR (LBRCXM-609): Bad return status from RCX run. 0xff00 INFO (LBRCXM-709): ***** QRC terminated abnormally *****
