I am trying to use si to generate a netlist for a 3rd party simulator using OASIS. My si.env file has: loadContext("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc- linux2.4/tools.lnx86/dfII/etc/context/analog.cxt") loadContext("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc- linux2.4/tools.lnx86/dfII/etc/context/oasis.cxt") loadContext("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc- linux2.4/tools.lnx86/dfII/etc/context/asimenv.cxt") simLibName = "AA" simCellName = "pmc_3v" simViewName = "schematic" simSimulator = "mysimulator" When I try to run si . -batch -command nl I get the following error: *Error* eval: undefined function - asiRegisterTool I tried to load the asiRegisterTool procedure but now get other errors: loadContext("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc- linux2.4/tools.lnx86/dfII/etc/context/analog.cxt") loadContext("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc- linux2.4/tools.lnx86/dfII/etc/context/auCore.cxt") load("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc-linux2.4/ tools.lnx86/dfII/etc/context/auCore.ini") load("/_TOOLS_/dist/cadence-ic-/5141-isr20090501/i686-pc-linux2.4/ tools.lnx86/dfII/etc/context/oasis.ini") *Error* arrayref: can't handle nil["sim-env:simulator-started"] *Error* load: error while loading file - "/_TOOLS_/dist/cadence-ic-/ 5141-isr20090501/i686-pc-linux2.4/tools.lnx86/dfII/etc/context/ oasis.ini"
