Netlisting Unsuccessful for PEX Simulation in ADE/ADEXL

shbmsra12

Hi All,

I'm encountering an error while generating the netlist in ADE/ADEXL for post-layout simulation of my design. I have used the spectre output (PEX Output) as input of few block of my interest in the config view. When I tried to generate the netlist to make sure good to go for simulation, But the netlist didn't generate and it throws an error. The Error in the CIW is given below.

INFO (SCH-1170): Extracting "mux_v2_w_predriver_final schematic"
INFO (SCH-1426): Schematic check completed with no errors.
INFO (SCH-1181): "tx_2021 mux_v2_w_predriver_final schematic" saved.

I tried to trace it back if there is some error in the PEX generated spectre output file. But it doesn't shows any error in CIW. The contect of the CIW window is given below.

    I don't know which sub-version of the IC tools you are using (it's always useful to know this, as the forum guidelines request), but one example of where I found this had happened before (from doing some searching, as I've not seen it myself) is where you have a discrepancy between the CDF termOrder and the file you are including (I'm not sure why that would cause a failure like this to be honest. I would however say that using sourcefile in the hierarchy editor isn't the easiest approach, as you need to edit the spectre simulation information in the CDF for the cell to ensure that the termOrder matches that in the included file. Better to create an extracted view or smart view (if using Quantus QRC), or to create a DSPF file from the extraction tool and then include that via the dspf include on Setup->Simulation Files.

    Hi Andrew,

    I'm sorry for not mentioning the version of the tool. I'm Using IC6.17-64b.78 and Spectre version is 15.1.0.257. I vouch about your comment regarding discrepancy between CDF termOrder in schematic netlist and PEX generated netlist. Before utilizing the PEX generated netlist as sourcefile the CDF termOrder needs to arranged as per schematic netlist. Which I had done manually here because earlier Calibre extracted view was taking a lot time to load and simulate. But thanks for telling to use DSPF file. I'll use DSPF from now onwards.

    Regarding the netlist generation,  I was not able to generate the netlist from ADE-L/ADE-XL. But when I fired the simulation through ADE-XL, It ran and I was able to generate the netlist from  the corners tab in the result window in ADE-XL. Eventually the simulation completed successfully as well.  But This is kind of look weird to me on the behavior of the tool.

    I've no idea what has gone on here - I suggest you contact customer support (although ADE XL is end-of-support, so you might want to check with ADE Assembler first).

    Yeah,

    For now, It's working fine. It kind of weird behavior of tool, I don't know. But, I'll surely I'll check with the customer support. Thanks for your Help.

    Best,
