Model Circuits in Schematics without Writing Codes

    GLISTER™ is a graphical user interface to XMODEL™ and MODELZEN™ integrated into the Cadence® Virtuoso® Design Environment. With GLISTER™, you can easily compose analog models in schematic forms and run XMODEL™ simulations without writing any codes.

Model Building with XMODEL™ Primitive Symbols

    GLISTER™ provides the rich set of XMODEL™ primitives as schematic symbols and can netlist them into SystemVerilog models. Hence, writing models with GLISTER™ simply means placing primitive symbols on a schematic and connecting them with wires. No coding is necessary! Composing models with GLISTER™ is even easier with the on-line documentations integrated into the Cadence® Virtuoso® Design Environment.

Mixed-Signal Hierarchical Netlisting

    GLISTER™ understands that your schematic models may contain different types of signals connecting digital and analog components, such as wire, real, xbit, and xreal. When netlisting the schematics into System Verilog models, GLISTER™ can automatically determine the proper type of each signal and insert type-coercing connectors as necessary.

XMODEL-SPICE Co-simulation Support

    When both circuit and model views co-exist in the design hierarchy, GLISTER™ prepares necessary files for XMODEL-SPICE co-simulation, including the System Verilog model files, SPICE/Spectre netlists, and mixed-signal simulation control files. The view for each cell or instance can be selected using the Cadence® Hierarchy Editor. The GLISTER™ Testbench Editor provides a uniform interface to different simulators including Synopsys®’s VCS® and XA and Cadence®’s NCVerilog® and APS.

Integrated Testbench Management

    With GLISTER™’s Testbench Editor, you can define XMODEL™ testbenches as cellviews in the Cadence® design database, specifying the simulation options, hierarchy configurations, extra source files, etc., all using a graphical user interface. Also, each testbench cellview can be exported as a simulation directory containing a Makefile and source files, allowing batch processing from the command line.

Cross-probing Support for XWAVE Waveform Viewer

    After the simulation is run, you can view the waveforms using XWAVE or any other waveform viewer supporting FSDB format. GLISTER™ supports interactive cross-probing for quick and easy selection of signals to view.

Graphical User Interface for MODELZEN™

    GLISTER™ also serves as a GUI front-end for MODELZEN™, enabling you to auto-generate models from circuits just with a single mouse click! With GLISTER™, you can assign custom MODELZEN™ properties to individual pins or instances on a schematic, tailoring the way the model is generated. For instance, you can change the data type of each I/O port or adjust the accuracy level of each instance model. GLISTER™ can also import the generated models into the Cadence® design database and maintain the models up-to-date.

Cadence® Virtuoso® Analog Design Environment (ADE)

    GLISTER-ADE integration allows you to choose “XMODEL™” as one of the supported simulators from ADE sessions and perform key GLISTER™ tasks such as composing testbenches, generating netlists, running simulations, and viewing waveforms, all using the familiar ADE menus and commands.
