Adding Liberty to Hurricane bridge + python wrapper

[etyloppihacilem]

Adding Python wrappers, fixes across liberty lib

Tested and fixed Liberty to Hurricane bridge

Setting proper ownership of liberty library : when mapped to Hurricane, ownership is transferred to database.

How to use

Pdk configuration :

from coriolis import CRL

LibertyLib = CRL.LibertyLibrary(filepath="/.../path/to/liberty.lib")
if LibertyLib.load():
    print("Library file", liberty, "was successfully parsed.")
else:
    print("[ERROR] parsing of ", liberty, " was not successful. CG will fail.")
LibertyLib.mapLibertyToDb() # at this point db owns LibertyLib
print("Liberty informations were added to Hurricane database.")

Basic usage :

def example():
    from coriolis.Hurricane import DataBase
    from coriolis.CRL import getLibertyGroupFromCell

    db = DataBase.getDB()
    if db is None:
        print("There is no database yet...")
        return
    root = db.getRootLibrary()

    for lib in root.getLibraries():
        print("LIB :", lib.getName())
        for cell in lib.getCells():
            print(cell.getName())
            grp = getLibertyGroupFromCell(cell) # cell = Hurricane.Cell
            if grp is None:
                print("Pas de LibertyProperty attachée à cette cell")
            else:
                attr = grp.getAttribute("area")
                area = attr.getValue() if attr is not None else None
                print("area =", area)
