S家PT dmsa ECO 带location的icc2innovus脚本:亲测有效

hevendai

基于论坛的脚本修改了一下,折腾了一天,弄了个带lcation的:
首先在pt_shell添加下面 option:
set all_lef_list " \
     ./pathto/sc12mc_tech.lef  \
     ./pathto/sc12mc_logic0040ll_base_lvt_c40.lef \

                    "

set DECAP_CELLS   "FILLCAP4_A12TL40 FILLSGCAP4_A12TL40 FILLCAP8_A12TL40 FILLSGCAP8_A12TL40 FILLCAP16_A12TL40 FILLSGCAP16_A12TL40 FILLCAP32_A12TL40 FILLSGCAP32_A12TL40 FILLCAP64_A12TL40 FILLSGCAP64_A12TL40 FILLCAP128_A12TL40 FILLSGCAP128_A12TL40 FILLCAP128_A12TL40 FILL64_A12TL40 FILL32_A12TL40 FILLCAP16_A12TL40 FILL8_A12TL40 FILL4_A12TL40 FILL2_A12TL40"
set FILLER_CELLS  "FILL1_A12TL40 ENDCAPTIE3_A12TL40 FILLTIE8_A12TL40 "
set FILLER_CELL_NAMES_PT   "$DECAP_CELLS $FILLER_CELLS"

.......................source ../scr/icc_2_innovus.tcl  如下:只对insert_buffer做了match修改,其他请类似修改:

set in_icctcl_file   [open ${file_fix_hold_icc} r+]
set out_innovus_file [open ${file_fix_hold_inn} w]

while {[gets $in_icctcl_file line]>=0} {
    #current_instance#for root instance
    if {[regexp {current_instance$} $line ]} {
        set hinstGuide $design
        set hier_inst  ""
        puts $out_innovus_file "#$line"
        continue
    }

    #current_instance u_cic#some icc has {} some has no {},so we add [\{]* to match
    if {[regexp {current_instance [\{]*(\S+)[\}]*} $line uselessvar_a hier_inst]} {
        set hinstGuide  $hier_inst
        set hier_inst   $hier_inst/
        puts $out_innovus_file "#$line"
        continue
    }

    switch -regexp $line {
        {size_cell} {
            regexp {size_cell\s*\{(\S+)\}\s*\{(\S+)\}} $line uselessvar_a inst cell_type
            puts $out_innovus_file "#$line"
            puts $out_innovus_file "ecoChangeCell -inst $hier_inst$inst -cell $cell_type \n"
        }

        {remove_buffer} {
            regexp {remove_buffer\s*\[get_cells\s*\{(\S+)\}\]} $line uselessvar_a inst
            puts $out_innovus_file "#$line"
            puts $out_innovus_file "ecoDeleteRepeater -inst $hier_inst$inst -nonPhysical \n"
        }

        {insert_buffer} {
            #insert_buffer [get_pins {sram_csn_reg/QN}] XXX -new_net_names {FIX_ECO_NET_xx} -new_cell_names {FIX_HOLD_ECO_CELL_xx}
            #insert_buffer [get_pins {U12/A}] XX -new_net_names {FIX_HOLD_ECO_NE_XX} -new_cell_names {FIX_HOLD_ECO_CELL_xx} -location {547.192 371.7} -orientation N
            regexp {insert_buffer\s*\[get_pins\s*\{(\S+)\}\]\s*(\S+)\s*-new_net_name.*\s*\{(\S+)\}\s*-new_cell_name.*\s*\{(\S+)\}\s*-location\s*\{(.*)\}} $line uselessvar_a term cell_type new_netname new_cellname cell_position
            puts $out_innovus_file "#$line"
            puts $out_innovus_file "ecoAddRepeater -term $hier_inst$term -cell $cell_type -new_net_name $new_netname -name $new_cellname  -hinstGuide $hinstGuide -loc {$cell_position} \n"
        }
    }
}

close $in_icctcl_file
close $out_innovus_file

运行后生成innovus运行的tcl如下:

据我了解，pt吐出的physical aware的eco脚本有一些hier bug，特别是对于同一net连续插入buff的时候。

hevendai

我目前没碰到,这个具体是连续插入buffer后eco脚本有location问题吗?

ASIC_Peng

请教下  location 是什么意思，你的pt 是什么版本，为啥我的insert buff 没有这个location 选项解释？
