creating a netlist

I duplicated your design data  to test the skill code:

C:\Temp>
C:\Temp>cat test.csv
BGA,A3,BGA,BGA,BGA_PAD,27000,-29000,VSS
BGA,A4,BGA,BGA,BGA_PAD,26000,-29000,VSS
DIE,30469,DIE_NEW,DIE_NEW,FC_PAD,23315,-14115,NC
DIE,30470,DIE_NEW,DIE_NEW,FC_PAD,23315,-14315,NC

C:\Temp>wc test.csv
  4   4 182 test.csv

C:\Temp>

I did not have any issues loading the netlist...

C:\Temp>tail allegro.jrl
\t (00:20:45) Autosave successful
\w (00:20:45) Autosave time limits are: 5 to 300 minutes
\i (00:20:59) skill csv_net_import
\i (00:21:03) fillin "test.csv"
\t (00:21:03) 4 lines read, 4 net assignments made, 0 errors found
   (00:21:03) t
\i (00:22:42) save
\i (00:22:42) generaledit
\i (00:22:47) exit
\t (00:22:47)     Journal end - Mon Aug 19 09:27:29 2024

Are you using the latest skill code I posted 10 days ago?

thank u for ur response, david.  i really appreviate it.

yes i used ur latest skill code posted 10 days ago.

with the first tow, i get this.

this works fine as all 4 nets r imported.

but without the first row, i get this.

one last net is not imported.

this is weird.  maybe it is because i use apd so the format may be slightly different.

I do not believe you are using the latest skill code, since the summary line does not include the error count as shown from my test:

4 lines read, 4 net assignments made, 0 errors found

Also, do the files for 'DIE' symbol have pin number 29332 ?

thank u david for ur response.

i double checked the skill code and confirmed that I use the latest one which does not show "0 errors found" on my command line, weird.

i changed the netlist slightly (changing the pin #30470 to pin #29332) to see how the skill code assigns the nets to the pins.

i noticed before importing the csv file, i need to clear all the nets already assigned to the pins by using deassign net.

otherwise, if pin #30470 is assigned to NC prior to the csv import and the csv file does not contain pin #30470, then pin #30470 would still stay with NC after importing the csv file.
