That's what the article shows. cir file. While it can can be run in a Nov 10, 2009 · To setup Cadence to the specific model library, you need to define or include the available model library. The syntax in the model file for Spectre is fairly simple to read. scs file that calls the verilog-A model. I've attached the script as file "create_bus_save_file. 1. scs file. startup projectDir The path of all the simulation directories will be located at the directory named in this string. cir file in the Setup -> Simulation Files -> Psipice files, and without doing any modification on the original . Create a text file (called, say, saveop. scs file, outside of the curly braces of the montecarlo analysis statement. I have several . scs file and write the following command to use model library. As described in the documentation for this library, you need to include: I can see the subcircuit clearly in the model file . The contents of the two files look quite normal to me. scs file and please give me some suggestion. Save the diode model in a text file with . I am thinking it maybe because of loading several files in OCEAN, or invoking the The Cadence Design Communities support Cadence users and Dear Andrew, When added envSetVal("spectre. ) The Cadence Design Communities support Cadence users and technologists interacting to exchange ideas, news, technical information, and best Mixed results though. scs files of both simulations - i. If someone can answer my question then point me to what part of the documentation would help with understanding more about . scs with the contents: Winrar or 7zip should work to open an SCS file unless it's locked from the original author if it is unlocking it is hacking [ external image ] Top. scs file in a maestro view with the stimulus field. In the ADE-L state I define a variable with the path, to be resolved at netlisting time: The Cadence Design Communities within the Cadence Analog Design Environment. The community is open to everyone, and to provide the most value, we 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. Regards First of all, this is not really a supported flow - the runSimulation script is a means to an end in the simulation flow, and it's not really there for you to run batch simulations afterwards. Include files. I have asked Cadence Technical Support and they have given me this procedure: Procedure #1: 1. 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: 1. cdnshelp from the MMSIM/SPECTRE installation). Ah interesting, there is a file (I was initially looking for a statement using grep) called spiceCB. Cancel; Vote Up 0 Vote Down; 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). PS: note for the future: strcat is resolved after netlisting, i. bbn is the broadband spice file that I was trying to use. simulator lang=spectre : This model is I'm new to the Cadence Spectre, I want to know how can I use a Hspice nmos/pmos model in the Cadence Spectre tool. To simulate using spectre from the command line go to spectre simulation from the command line. com/2015/11/03/error-input-scs-is-an-instance-of-an-undefined-model/while trying to simulate a simple I-V curve from Sir I have attached verilog-A and . Is that possible ? What would be the syntaxe ? input. how can I use these in cadence? I tried installing PSP/Simkit, but this didn't seem to contain the files I need to install a library (tech file etc). 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" suffix so spectre knows it is in spectre rather than SPICE syntax), containing one of the statements I mention in my previous post, save it, and then in ADE you can reference it as a file in the model libraries form. I usually include the added save nets file as a Simulation file and NOT as a models file. Then create the symbol, cadence will recognize the number of input/outputs based on the subcircuit. scs I got a great number of errors, but all are similar. MasterPlane Newbie level 4. My expectation is that you've accidentally specified the PWL file name on the ipwlf source as "stimulus" rather than "stimulus. But actually I have never seen this window before, normally I set corners at the Data view panel which is easy. scs file, and tool versions? I think with this information, I could provide some added thoughts thegon. scs file to use them. Oct 19, 2012 #1 M. scs file in the /test directory, I have used them. scs netlist file. m and *. txt". 2V rather than 2V. I think you can check this by examining your input. I have typed this line : spp -convert ths4131_netlist. This is why it's worth checking the whole file, not just the last line. a. scs). scs file and loaded that as a model in my corner setup. If you want to run AMS simulations (this is a mixed-signal simulation, not a spectre simulation, so the flow is more complex than Shawn was describing, which is for spectre) from batch, the There is a model file in Cadence ADE installation. Choose Jan 21, 2016 · Note: It’s possible that your simulation will encounter a “fatal error” in the “input. Regards, Andrew. I go to Setup -> Model Libraries and add the save. scs, or download this file instead. irun: *E,FMUK: The type of the file (. If kp is given, uo is calculated from uo = kp/C ox, whether uo is given or not. g. scs file in my cadence directory with the following content :. scs file and noise file and run them from the spectre command. scs, amsbind. In response to this, I use method 3, put the . It will now parse the file. This might explain why your attempt to exclude the bulk node terminal currents using the syntax "*:b" is not excluding the bulk node currents. So to run spectre I give the command spectre filename. scs in runSimilation(the input file). scs;section1 path2. with a ". scs" suffix is a bit confusing, because that suggests it is in spectre netlist syntax, whereas in fact it's a "nodeset" or "ic" file (which is just node-value pairs). When i do ADE ->netlist and run and see the generated netlist the netlist still has 10 files insted of five files . Both should be small enough files to include. scs"). I am trying to set up my stimulus properly so I wrote this . To setup Cadence to the specific model library, you need to define or include the available model library. mc run. Products The Cadence Design Communities support Cadence users and technologists interacting to exchange ideas, news, technical information, and best practices to solve problems spectre MY_SPECTRE_NETLIST. Paste the file in the directory where Cadence looks for simulation files. scs” by going to. /amsControlSpectre. scs - that seems very strange; The Cadence Design Communities support Cadence users and technologists interacting to exchange ideas, The second approach would be to create a file (with a . Open any schematic, select Design -> Create Therefore I think it would be pretty better to have copy procedure of netlist/input. I typically write out the signals to a text file in order to do postprocessing on these outside the Cadence design environment. scs file that I modified, but the simulation uses the old one. Alternatively, use the -I <path> command-line option to specify the path to the file and rerun the simulation. Anyways, below is a snapshot of all the different files ADS can generate from a touchstone file. cdsenv Look for the string asimenv. Maybe because I am running OCEAN from the server. Ensure that the file exists and the path to the file is correct. Site initialization files are provided by the system administrator and are used to set up a common environment for the various Cadence tools and for the chosen technology. the options statement, and all the analysis statements)? Also can you say which subversion of the IC tools (Help->About in the CIW) you're using, and also the precise spectre version (this will appear at the top of the spectre. scs file :) If you are referring to the model. plwmj unhipz qqanaus ycdri mjhrki gqx jgsz qmeu zzhp kohe
