Toggle Flash

Toggle Flash

Toggle Flash provides an smart way to verify the Toggle Flash host controller or Toggle Flash memory model of a SOC or a ASIC. The SmartDV's Toggle Flash is fully compliant with standard Toggle Flash Specification and provides the following features.

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

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

Features
  • Compliant with Toggle Flash JESD230/ JESD230A/ JESD230B/ JESD230C/ JESD230D specifications.
  • Supports SDR, Synchronous DDR, NV-DDR2 and Toggle-mode DDR data interface.
  • Supports all mandatory and optional commands.
  • Supports 16 bit bus width operations.
  • Supports Read ID commands.
  • Supports Synchronous reset and Reset LUN commands.
  • Supports Multi-plane commands.
  • Supports Write protect pin for multiple function.
  • Supports Data training.
    • Supports DCC training.
    • Supports Read DQ training.
    • Supports Write DQ training.
  • Supports pausing Data Input and Output.
  • Supports Random Data Out commands.
  • Supports Get features and Set features commands.
  • Supports Feature Address Registers.
  • Configurable speed grades for all data interface.
  • Supports copy back programming.
  • Source Synchronous data interface supports Clock Stop feature.
  • Supports dual data bus.
  • Supports Small Data Move command for both Program and Copy back operations.
  • Rich set of configuration parameters to control Toggle Flash functionality.
  • Supports constrained randomization of protocol attributes.
  • On-the-fly protocol and data checking.
  • Protocol checker fully compliant with Toggle Flash Specification with versions JESD230/ JESD230A/ JESD230B/ JESD230C/ JESD230D.
  • Status counters for various events on bus.
  • Callbacks in host, slave and monitor for user processing of data.
  • Toggle Flash Verification IP comes with complete test suite to test every feature of Toggle Flash specification.
  • Models, detects and notifies the test bench of significant events such as transactions, warnings, timing and protocol violations.
  • Built in functional coverage analysis.
  • Supports Callbacks, so that user can access the data observed by monitor.
Benefits
  • Faster testbench development and more complete verification of Toggle Flash designs.
  • Easy to use command interface simplifies testbench control and configuration of Host and Slave.
  • Simplifies results analysis.
  • Runs in every major simulation environment.
