SRAM Memory Model

Overview

SRAM Memory Model provides an smart way to verify the SRAM component of a SOC or a ASIC. The SmartDV's SRAM memory model is fully compliant with standard SRAM Specification and provides the following features. Better than Denali Memory Models.

SRAM Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

SRAM Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.

Key Features

  • Supports SRAM memory devices from all leading vendors.
  • Supports 100% of SRAM protocol standard.
  • Supports all the SRAM commands as per the specs.
  • Supports Automated power down when deselected.
  • Supports write cycles operation.
  • Supports read cycles operation.
  • Supports complete static memory without clock and timing strobe.
  • Supports embedded error-correcting code for single bit error correction.
  • Supports equal address and chip enable access times.
  • Supports following device types,
    • X4
    • X8
    • X16
    • X32
  • Checks for following
    • Read/Write Command rules etc.
    • All timing violations.
  • Supports full-timing as well as behavioral versions in one model.
  • Supports all timing delay ranges in one model: min, typical and max.
  • Protocol checker fully compliant with SRAM Specification.
  • Models, detects and notifies the test bench of significant events such as transactions, warnings, timing and protocol violations.
  • Constantly monitors SRAM behavior during simulation.
  • Built in functional coverage analysis.
  • Supports Callbacks, so that user can access the data observed by monitor.
  • Supports the Windbond, Motorola, Cobham and Cypress part numbers CY7C199CN, CY7C1049DV33, CY62256N, CY62162G/CY62162GE, CY7C1062G/CY7C1062GE.

Benefits

  • Faster testbench development and more complete verification of SRAM designs.
  • Easy to use command interface simplifies monitor control and configuration.
  • Simplifies results analysis.
  • Runs in every major simulation environment.
