Remapping a Package Netlist

SIwave can map a previously extracted package netlist into the footprint of a new chip.

For instructions on exporting a PLOC file, see: Exporting CPA RLGC Results.

Requirements:

• The model has been extracted using an old PLOC file and needs to be remapped into a new PLOC file.
• There is a preexisting adsCPA folder. The new PLOC will be mapped to and update the annotated and ASCII PLOC files in this folder.
• The number of nets in the new PLOC matches that of adsCPA.
• The preexisting package has been extracted using an M x N grid, with Channel setup

Remapping Commands:

Remapping is performed from the command line, using speng.exe:

speng.exe <path_to_adsCPA_folder\adsCPA\> <path_to_config_file\ploc_remap_config.txt> <path_to_new_ploc_file\newplocfile.ploc> -reassign_ploc_gridbased

The command window will track remapping progress.

The adsCPA folder is expected to contain a file named cpa_annotated.ploc. Once remapping has finished, cpa_annotated.ploc will be overwritten. A copy of the original file will be available as cpa_annotated_old.ploc.
