  • SPICE 1: Tutorial
    SPICE 1: Tutorial Chris Winstead January 15, 2015 Chris Winstead SPICE 1: Tutorial January 15, 2015 1 / 28 Getting Started SPICE is designed to run as a classic console tool, aka a terminal command. If you are unfamiliar with the Linux terminal, you should spend some time to get acquainted with basic terminal commands, and how to organize and navigate directory structures (a directory is often called a \folder"). I prepared a quick-start terminal tutorial that you can review here: https://electronics.wiki.usu.edu/Linux_Tutorial If you plan to use NGSpice in the lab (which I recommend), then you may want to check out our NGSpice wiki page: https://electronics.wiki.usu.edu/NGSpice You can also find NGSpice information and the full manual here: http://ngspice.sourceforge.net/ You will also need to choose a text editor for preparing your SPICE files. I like to use Emacs (it has an optional SPICE mode that is pretty handy). Most students prefer to use GEdit. You can launch these editors from the terminal. Chris Winstead SPICE 1: Tutorial January 15, 2015 2 / 28 Creating a Project First, you'll want to open a terminal window and create a directory tree for your work this semester. You could setup your directory tree using these commands: cd mkdir 3410 cd 3410 mkdir spice cd spice mkdir lab1 cd lab1 Here the cd command is used to change directories, and the mkdir command is used to create a directory. Chris Winstead SPICE 1: Tutorial January 15, 2015 3 / 28 Create a new SPICE file SPICE files (often called \decks" for historical reasons) are plain text files.

  • Circuit Optimisation Using Device Layout Motifs
    Circuit Optimisation using Device Layout Motifs Yang Xiao Ph.D. University of York Electronics July 2015 Abstract Circuit designers face great challenges as CMOS devices continue to scale to nano dimensions, in particular, stochastic variability caused by the physical properties of transistors. Stochas- tic variability is an undesired and uncertain component caused by fundamental phenomena associated with device structure evolution, which cannot be avoided during the manufac- turing process. In order to examine the problem of variability at atomic levels, the `Motif ' concept, defined as a set of repeating patterns of fundamental geometrical forms used as design units, is proposed to capture the presence of statistical variability and improve the device/circuit layout regularity. A set of 3D motifs with stochastic variability are investigated and performed by technology computer aided design simulations. The statistical motifs compact model is used to bridge between device technology and circuit design. The statistical variability information is transferred into motifs' compact model in order to facilitate variation-aware circuit designs. The uniform motif compact model extraction is performed by a novel two-step evolutionary algorithm. The proposed extraction method overcomes the drawbacks of conventional extraction methods of poor convergence without good initial conditions and the difficulty of simulating multi-objective optimisations. After uniform motif compact models are obtained, the statistical variability information is injected into these compact models to generate the final motif statistical variability model. The thesis also considers the influence of different choices of motif for each device on cir- cuit performance and its statistical variability characteristics. A set of basic logic gates is constructed using different motif choices.

Miniaturization has been the art used in CMOS (complementary metal oxide semiconductor) for decades, to handle these energy and speed issues, however the technology is facing physical constraints. Superconducting circuit technology is a suitable candidate for beyond CMOS technologies, but faces challenges on its design tools and design automation. In this study, methods to model single flux quantum (SFQ) based circuit using hardware description languages (HDL) are implemented and thereafter a synthesis method for Rapid SFQ circuits is carried out.

  • XSCHEM PDF Manual
    XSCHEM 0.29 Manual and Tutorials XSCHEM : schematic capture and netlisting EDA tool Xschem is a schematic capture program, it allows creation of hierarchical representation of circuits with a top down approach . By focusing on interfaces, hierarchy and instance properties a complex system can be described in terms of simpler building blocks. A VHDL or Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives very good speed performance, even on very big circuits. The user interface is built with the Tcl-Tk toolkit, tcl is also the extension language used. Features hierarchical schematic drawings, no limits on size any object in the schematic can have any sort of properties (generics in VHDL, parameters in Spice or Verilog) new Spice/Verilog primitives can be created, and the netlist format can be defined by the user tcl extension language allows the creation of scripts; any user command in the drawing window has an associated tcl comand VHDL / Verilog / Spice netlist, ready for simulation Behavioral VHDL / Verilog code can be embedded as one of the properties of the schematic block, Xschem runs on UNIX systems with X11 and Tcl-Tk toolkit installed.
