![]() Then clickĪ new dialog box will pop up to ask you whether a technology file should beĪssociated. We are going toĬreate our own library to manage all the cells that will be eventually created. The library 'NCSU_Devices_FreePDK45' contains a few cells representing the PMOSĪnd NMOS transistors we are going to use to design our circuit. Virtuoso, and the cells are grouped into libraries for management. Logically, the design of a single component is called a cell in Our designs are physically stored as files and managed by the directoryĮce429. Parameters for the 45nm technology that we will use throughout the semester. Also note that the messages showing in the Log window indicate that theįreePDK45 library is loaded successfully. Manager window on the right doesn't show, you can bring it up by clicking Tools→Library Manager from the Log You should at least see the Virtuoso Log window on the left. WARNING: if you attempt to move the working directory, you shouldĪlso update the 'cds.lib' file within the directory. It again the next time you work in the same directory. Note: once a working directory is created, you don't need to create Which are required by Virtuoso and other tools. This command copies various files into the directory, You should initialized it by the command: ![]() You can choose a different name but I would use Therefore necessary to organize your designs into a single directory and manageįirst of all, the directory can be created using the following command: May refer to each other that you need to manage for labs and projects. Manage a large number of files, not to mention more complicated designs which Inverter Schematic using Virtuoso a) Creating aĪll your designs are stored on the ECE UNIX network as various files andĪdditional files are required for Virtuoso and other tools to functionĬorrectly - even the inverter design in this tutorial will require you to close ther current terminal and open a new one. Use "gedit ~/.cshrc" open it, put those three 'source' command at the end of the file and save it. This file will be automatically executed every time you launch a terminal. Note: You can also put the above three 'source' commands into your shell configuration file, which is located in your user directory, and named '.cshrc'. If the setup is correct, you should see where Virtuoso You can validate the environment setup by: ![]() Source /import/scripts/synopsys2012.cshrc (add this command when you use saturn/uranus servers) Source /import/scripts/hspice.cshrc (add this command when you use saturn/uranus servers) Source /import/scripts/ece429.cshrc (all servers) Window, use the following command to initialize the environment variables: You can start the terminal by right-clicking on the desktop and Logged into an ECE workstation or have established a VNC connection to an ECE Therefore, the first step is to bring up a Linux terminal, sometimes knownĪs a console, which allows you to input Linux command. Started from the command line as many environment variables should be assignedĬorrectly so Virtuoso can find various libraries and tools. Setting up Your Account Environment (Use only Endeavour server: )Īlthough the Virtuoso platform works under a UNIX/Linux GUI, it is usually If you are inside of Illinois Tech Network, skip to the next step. Starting Spring 2021, Remote Desktop Connection must be connected via IIT VPN connection if you are outside of Illinois Tech Network.
