Hi,哪位大佬在s家40nms SMIC 40nm LOGIC0040LL LVT 1.10 Volt SC12 High Performance MC
用voltus做过IR drop分析, 生成一个sram macro pgv lib:
最近generate_pg_library -output ../output/macro_pgv
需要set_pg_library_mode \
-celltype macros \
-ground_pins VSSE \
-power_pins {VDD 1.1 VDDPE 1.1 VDDCE 1.1} \
-cell_list_file ../data/macro.list \
-spice_subckts $macro_cdl_file \
-gds_files $macro_gds_file \
-gds_layermap ../data/gds_qrc.map \
-current_distribution propagation \
-spice_models $spice_model_file \
-spice_corners {tt bjt_tt dio_tt res_tt var_tt mom_tt ldmos_tt} \
-stop@via pdfCont \
-extraction_tech_file ${QRC_TECH_FIL}
官方pdk里面没找到qrc和gds都mapfile.根据经验看virtuos下gds map文件写了一个gds_qrc.map:
diff pdiff gds 43
diff ndiff gds 40
poly poly gds 30
via pdfCont gds 50
#via ndfCont gds 50
#via polyCont gds 50
metal metal1 gds 61
via via1 gds 70
metal metal2 gds 62
via via2 gds 71
metal metal3 gds 63
via via3 gds 72
metal metal4 gds 64
via via4 gds 73
metal metal5 gds 65
via via5 gds 74
metal metal6 gds 66
via via6 gds 75
metal metal7 gds 67
via via7 gds 121
metal metal8 gds 120
via via8 gds 123
metal metal9 gds 122
via PA gds 80
metal alpa_inter gds 83
有哪位大佬能帮忙看下这个map是否ok?
另外个人有一个疑问, qrc的tech file中有3个contact 层:polyCont pdfCont ndfCont,但是在virtuoso那边的stream文件中只有layer 50(CT)对应.
这个时候没法ndfCont 和 polyCont 也map 到50,这会不会有问题?
