Is it possible to tell ADE-L to include a file without needing to hard-code its path? This procedure works in Assembler, but fails in ADE-L: I put the file to include (say "input. Both should be small enough files to include. Create a text file (give it a ". This might explain why your attempt to exclude the bulk node terminal currents using the syntax "*:b" is not excluding the bulk node currents. I can't locate the CCR I was referring to before (I had a quick search but didn't find it). scs files. You could even copy the input. scs file to the model libraries section of ADE . Alternatively look at the documentation in cdsdoc. scs" suffix. So to run spectre I give the command spectre filename. scs" - make sure it has a . scs file and noise file and run them from the spectre command.

Alternatively, use the -I <path> command-line option to specify the path to the file and rerun the simulation. The file has an ". scs file that resides in the /stimulus/ subdirectory and was seemingly created by the netlister. Then create the symbol, cadence will recognize the number of input/outputs based on the subcircuit. The "input. In Explorer you can use Window->Toolbars->Results and then hit the little terminal icon which should open the terminal just above the netlist dir (assuming you're only running a single simulation and not sweeps or corners). scs" file is contained in the netlist directory. scs save I129. scs file in the netlist directory), I am displaying the transient analysis command for the test case I performed below: tran tran stop=210n errpreset=conservative noisefmax=10e9 noisefmin=1 \ new scs file is added to "tran_noise test".

Recreating the netlist without simulation would put the whole strcat() expression, and not just the result into the parameter in the input. Whether initial conditions on devices is controlled by the ic parameter for tran analysis, or the force parameter for dc. On enabling either of the options and running UNL netlisting, the analog blocks will be netlisted in the pureAnalog. scs - it seems to have one in memory that it uses. Compare the two netlists (files "former_netlist" and "netlist" as well as "former_input. At first it seemed to me it adds it to selected models, but it is not. scs with the contents: Please share the input netlist (input. scs suffix so it is interpreted in spectre syntax). I am trying to include a file in spectre. scs file causes all the output data to be written in a couple of files in the data directory 3 The file netlist should be in the same directory as the input. This will create a design variable (and global variable) called "SAVEFILE". scs file, and tool versions? within the Cadence Analog Design Environment. scs file :) I tried to look in the " */topinclude. 1. Coming back to my original question, you can put . You can access your “input. The CCR I mentioned is to add support for the paramset approach. scs" it is assumed to be spice format Usually it's a matter of setting up the CDF properly; there's at least one solution on sourcelink (now Cadence Online Support) on I am using an older version of Cadence which doesn't allow to use a design variable for a dc sweep analysis from the "Choosing Analysis" menu in ADE. The Cadence Design Communities support Cadence users and technologists interacting to exchange ideas, news, technical information, and best practices to solve problems and get the most from Cadence technology. scs".

If you use Simulation->Netlist->Display (or Create), this is the netlist passed to the simulator (and the file is called "input. Here's a I've tried looking through Help->Contents but I'm fairly new to cadence and there is a lot to read. Where partial/path is the beginning of a path pointing to some model files. So I wrote a verilog-A code where I After changing the CDF and clicking OK (I do not get the warnings shown in my first post now, as the file is accessible/writable), I head to Assembler and hit the green play button. In general, spectre and ADE don't care about the suffix of the files passed to the simulator - the only special case is that if it has a ". Copy/save the bsimmodels into the same directory and then start Spectre by typing: spectre 3_11. It really would help to see the warnings and errors you are getting - without that it's really hard to debug. MasterPlane Newbie level 4. a.

To peform spice simulation, type the command. I perform a DC sweep where I am sweeping the length of the device Mcp listed in the save. The manual does not mention the format/syntax to write aged model files, which I need to know. Oct 19, 2012 #1 M. Also, there are files for ESD moduling. scs") under the cell directory 2. Type full path (including filename) of any model(s) needed for sim It’s possible that your simulation will encounter a “fatal error” in the “input. out file. Press the "Build a database" button (the save icon with the green checkmark) or File->Extract (they're the same) It will check all is OK with the model, and ask you to generate a symbol (which will have pins called 1,2,3,4,5 etc) - move to whichever side of the symbol you want; You can then place an instance of this symbol in your circuit If you're just running the "runSimulation" script as provided in the netlist directory, then if using ADE L and this is a pure spectre (not APS) simulation, then by default it will be attempting to run in interactive rather than batch mode (unless you'd specifically set the environment to run in "batch" mode). A CCR is a "Cadence Change Request". g. You can leave the models from the first tutorial intact because we are changing the model name from nmos6012 to nmos6012p for parameterized. Choose Setup->Simulator/Directory/Host a. vams in the netlist directory. First, I would like to point out that your answer offers, most likely, a good workaround but does not address the main issue I've tried to highlight, namely that if you declare your design to be a netlist, it seems like OCEAN XL ignores all statements that follow the design() declaration, resulting in an input. I have also added this . I found below in the Support. " Now, switch to your current PDK (which you term "PDK change"). scs file included from the spectre view resolves the path relative to the location of that file - which is in the original library.

I have an EEPROM block that requires initialization. scs file and netlist files and can provide them to you. I think you can check this by examining your input. Dear Shawn, thanks for your reply. scs files that are part of a PSP model library. Ah interesting, there is a file (I was initially looking for a statement using grep) called spiceCB. I am using an empty netlist (only entry is simulator lang=spectre) and using a stimulus file, where I have only one include statement: include "RefClk. Choose Setup->Model Path a. Following is an example : Figure 4: UNL Netlist Using Spectre Putting it in the "Include Path" field is bound not to work, since that is a list of directories that it looks for relative files specified in the model files, stimulus file or definition files lists. as a model file, or a definitions file) in the setup where you have a spectre save statement in the include file (say called "saves. Or add "simulator lang=spice" at Hot Carrier Degradation Model for MOS Transistors >> Degraded model generation), there are two methods for generating degraded parameters, one of them being aged model files. raw file which I can view using a smartspice postprocessor. scs file for simulting table based verilog-A code in CADENCE?
