LayCir - Schematic Editor
LayCIR is a flexible and powerful full-function schematic capture environment developed particularly to enable circuit design engineers to enter schematics accurately, clearly and quickly. In addition, it provides the ability to cross-probe between schematic and layout views. LayCIR includes many powerful features including the availability of an unlimited hierarchy that can be navigated from the design entry window with a single command. It offers a rich selection of digital and analog net-list formats and is closely linked to simulation environments. When coupled with LayED, LayCIR provides a schematic or net-list driven layout mode in which the layout implementation is monitored using the schematic or net-list.

Highlights
  • Enables rapid entry of complex schematics
  • Includes comprehensive editing features
  • Provides easy navigation of design hierarchy
  • Allows calculation and display of parameters
  • Generates net-lists in various digital and analog formats
  • Flexibly programmable simulator interface to address any simulator
  • Build-in simulator interfaces for Keysight ADS and Symica
  • Enables schematic-driven layout (LayED)
  • Allows LVS and cross-probing with layout (LayED)
Feature Details
  • Graphical data may be created and edited in an hierarchical set of schematic drawings
  • Edit flexibility includes copying between windows and sub-window drag
  • Data elements include symbols, attributes, texts, wires, buses, bus taps, and pins (for wires and buses)
  • Unlimited bus widths
  • Deep "undo" stack (currently set at 64)
  • No limit on design size or complexity
  • Unlimited number of sheets in multiple sheet drawings
  • Unlimited depth of design hierarchy
  • Navigation of the design hierarchy is unrestricted and traversed from the design entry window
  • Symbols for both primitive and sub-circuits can be auto-generated or customized
  • Symbols, whether customized or auto-generated, have no port count limit
  • Symbols are characterized using user-defined attributes that may be calculated from other attributes
  • Schematics and symbols may be organized in an unlimited number of reference directories
  • Flexibility is provided for the naming format of nets and buses
  • Standard net-list output formats are provided (device and gate level – including HSpice, PSpice, Verilog, VHDL, Spectre).
  • Hierarchical integrity checks may be carried out (ERC)
  • Cross-probing between LayCIR and LayED may use the same system or different systems ("socket" connection)
  • Schematic-driven layout (SDLE) possible when used with LayED
  • Parametric cells sharing between LayCir and LayED
