ADE simulation files -- error

Thodoros

 Hello,

I am trying to assign a simulation file to a ADE run (ADE ->setup -> simulation files) which contains the simple that follows:

simulator lang=spectre
_vAddr\<3\> (Addr\<3\> 0) vsource val0=0 val1=0 period=500p width=250p type=pulse

 I have ic6.1.4 and when I execute "Netlist and Run" I get the following error:

 Error found by spectre during circuit read-in.
     ERROR (SFE-874): "/home/simop/simulation/sram_PCCA/spectre/schematic/netlist/stimuli/stem" 2: Unexpected operator "<".

What really happens is that at the ~/ ... /simulation/<design>/schematic/netlist/stimuli/ directory the copied stimuli file has errased the "\" character.

I really have to add that character and perform ADE ->Simulation ->Run in order to continue with the simulation.

Can I ovefrcome this?

Thanks,

Thodoros

    The stimulus file goes through a mapping process which allows "schematic" names to be used via the [#...] syntax. These get mapped into whatever was used in the netlist (via mapping). So you'd use something like this:

    v1 ([#bus<0>] 0) vsource type=sine freq=1M ampl=1
    v2 ([#bus<1>] 0) vsource type=sine freq=2M ampl=1.5
    v3 ([#bus<2>] 0) vsource type=sine freq=3M ampl=2.0
    v4 ([#bus<3>] [#/gnd!]) vsource type=sine freq=4M ampl=2.5

    Note that there is a bug in IC61X (CCR 752498) where this doesn't work in some cases. You need to use  

    envSetVal("asimenv" "mappingMode" 'string "oss")

    Before starting ADE. And you may need to do a Simulation->Netlist->Recreate to force it to renetlist after making the change. This changes the netlist mapping back to the IC5141 method (see http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:ViewSolution;solutionNumber=11334086 )

    Note that the instance names are presumably not that critical, so you can call them whatever you want (they don't need to map to a bus name)

    Regards,

    Andrew.
