Belgrade, Serbia – August 23rd, 2010 – HDL Design House has announced the VITAL HVT M25PX behavioral simulation model for Numonyx M25PX16, a 16 Mbit (2 Mb x 8) serial flash memory, with advanced write protection mechanisms, accessed by a high speed SPI-compatible bus, with clock speeds per line at up to 75MHz.
Apart from the standard serial flash memory instructions, the VITAL HVT M25PX supports two new, high-performance dual input/output instructions:
- Dual Output Fast Read (DOFR) instruction used to read data at up to 75 MHz by using both pin DQ1 and pin DQ0 as outputs
- Dual Input Fast Program (DIFP) instruction used to program data at up to 75 MHz by using both pin DQ1 and pin DQ0 as inputs
The VITAL HVT M25PX behavioral model completely simulates the functionality of real component behavior and all component timing behavior. This implies complete functionality, timing on inputs and outputs, all desired relations between input signals (setup/hold , pulse with, etc.) and all delays between inputs and outputs. VITAL model contains information about 3 values of timing parameters: minimum/typical/maximum. Timing parameters are loaded from SDF file at the elaboration phase and it is possible to use either minimum or typical or maximum values simultaneously for all timings. The VITAL HVT M25PX behavioral model detects timing violation and reports it by using standard VITAL functions. The code is written in Verilog and VHDL and the model is highly portable across a range of simulators.
Key Features:
- VHDL ’93, Verilog and VITAL’2000 compliant
- Requires VITAL’2000 library for correct compilation
- Timing backannotation by means of an SDF files
- Models are written at a behavioral level, do not reveal intellectual property, and are not synthesizable
- 75 MHz frequency in full voltage range
- Voltage range: 2.3/2.7..3.6 V
- 4 KB erasable sub sectors, 64 KB erasable sectors
- Dual I/O, thereby doubling the speed of data throughput (150 MHz)
- 16 Bytes of unique ID
- 64 Bytes of OTP
- Software and hardware write protect available
- Broad package offering: SO8N, SO8W, MLP 5 x 6 & SO16W, MLP 6 x 8
- Automotive certified parts available
The VITAL HVT M25PX behavioral model is used for board-level and/or system level verification. In test environment, the device under test (DUT) is connected to the VITAL HVT M25PX component.
The VITAL HVT M25PX 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.

VITAL behavioral models are products of close cooperation of HDL Design House (HDL DH) and Free Model Foundry (FMF) company. HDL DH and FMF have developed 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 HVT M25PX model and other VITAL models are available for download free of charge from the FMF website (http://www.freemodelfoundry.com).
