HDL Design House announces AT25DF161 VITAL behavioral model

Belgrade, Serbia – August 27th 2009 – HDL Design House has announced ATMEL AT25DF161 VITAL behavioral model, 16-Megabit, Serial Flash Memory (SPI). The AT25DF161 is a serial interface flash memory device designed for use in a wide variety of high-volume consumer based applications. The AT25DF161 VITAL behavioral model completely models all aspects of real component behavior/functionality. This includes the checks of all timing relations between input signals (setup/hold, pulse width, etc.) and all delays between inputs and outputs.

AT25DF161 VITAL Behavioral Model Key Features:
  • VHDL’93, Verilog and VITAL’2000 compliant models
  • Requires VITAL’2000 library for correct compilation
  • Timing backannotation by means of an SDF files
  • Tested on and compatible with Cadence’s NCSim and Mentor’s ModelSim simulators
  • Models are written at a behavioral level and are not synthesizable
Benefits and deliverables:
  • Easy to use
  • Simplifies system level verification process
  • Reduces product development costs
  • Speeds time-to-market
  • Standard-based for fast, easy integration
  • Allows efficient system level simulation/verification
  • VHDL and Verilog source code
  • Test bench with test cases to test the model
The AT25DF161 VITAL behavioral model can be used along with HDL DH SPI flash memory controller IP core (HIP 3100). The HIP 3100 IP core is an advanced controller for SPI flash memories which off-loads host CPU from direct data transfer control of SPI flash memory. The host CPU can program SPI controller specifying the type of data transfer (SPI instruction, address, data, etc) and SPI controller executes requested transfer. One of supported SPI flash memories is AT25DF161 and both SPI controller (HIP 3100) and AT25DF161 VITAL behavioral model can be used for system level simulations.

VITAL behavioral models are products of close cooperation of HDL Design House (HDLDH) and Free Model Foundry (FMF) company. HDLDH and FMF have developed a thousands of VITAL models. The VITAL model package consists of VHDL and Verilog source code, memory preload files (when appropriate), FTM and SDF files, test cases package file and documentation. The AT25DF161 model and other VITAL models are available for download free of charge from the FMF website (http://www.freemodelfoundry.com).
