IC614 netlist and openaccess

wighou

 Hello,

Could explain what is the relation between the netlist and openaccess. Using IC614, I have two files sch.oa and verilog.ams in the folder of my cellview. Is it possible to read and modificate the sch.oa with a tool of database gestion. Is this file used to generate the schematic ? The verilog.ams is generated during the netlisting ?

 Thanks in advance

    Hi

    I progressed in my skill study.

    I used the following procedure that I encountered on the web and tried to modify it to change all "p_res" in my schematic to 1e-6 ohm :

    procedure(cb(lib cell)
    ;let will allow you to access the cv and newlabel variables outside
    ;of this procedure
    let((cv newLabel)
    ;open the cellview as a database object and assign it to cv
    cv = dbOpenCellViewByType(lib cell "schematic" "" "a")
    ;for loop to go through all instances in this cellview
    foreach(instance cv~>instances
    ;open the property window -- this will display the window!
    geSelectObjectNoFilter(instance)
    ;check the cellname and change the bulk node (bn) property
    if(schObjPropForm->cellName->value == "p_res"
    then
    schObjPropForm->r->value = "1e-6"
    )
    ;close the form
    hiFormDone(schObjPropForm)
    geDeselectAll()
    );end foreach
    );end of let
    );end procedure

     But I obtain the error :

     ...
