Lattice's New Mixed Signal Design Software Simplifies Platform Management Design

Integration With Lattice Diamond Design Environment Delivers More Advanced Digital Design Options

HILLSBORO, OR, Jul 18, 2011  -- Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced release 6.1 of its PAC-Designer(R) mixed signal design software, with updated support for Lattice's Platform Manager(TM), Power Manager II and ispClock(TM) devices. Users designing with Platform Manager devices will now have access to the Lattice Diamond(R) 1.3 software design environment, which was also announced today. This integration of the PAC-Designer 6.1 and Diamond 1.3 design software tools will make more advanced digital design options available with Platform Manager products. An automated simulation environment, not previously available to Platform Manager designers, is a primary benefit of the design software integration.

"With the integration of PAC-Designer 6.1 and Lattice Diamond 1.3 software, our customers will be able to design and simulate Platform Manager devices at an even higher level of productivity while maintaining the ease of use for which PAC-Designer software is widely recognized," said Shakeel Peera, Lattice Director of Marketing for Silicon and Solutions.

New Automated Simulation Capability Whether testing the functionality of critical analog I/O pin functions controlled by the Platform Manager's internal CPLD, or checking the integration of enhanced digital control functions coded in Verilog or VHDL within the Platform Manager's FPGA control section, PAC-Designer 6.1 software integrates seamlessly with Diamond 1.3 design tools to compile the entire design, create the necessary stimulus template file and then automatically generate initial timing waveforms within the Aldec Active-HDL simulator. This previously complex, manual design flow has been optimized and automated in PAC-Designer 6.1 software to generate all the necessary design files and deliver the initial timing flow diagram with just the click of a mouse.

Comprehensive Analog and Digital Design Support PAC-Designer 6.1 software provides a GUI-based design methodology for analog engineers that uses intuitive dialog boxes to configure the Platform Manager's analog sections; LogiBuilder design methodology to integrate power management functions into the on-chip CPLD; and LogiBuilder or Lattice Diamond Verilog/VHDL design methodology to integrate digital board management functions into the FPGA section of the Platform Manager device.

PAC-Designer 6.1 software includes four reference designs specifically targeted for the Platform Manager development kit, including Fault Logging and Monitoring, Enhanced Closed-loop Trim, Long Delay Timers and ADC Voltage Measurement. Eleven more reference designs compatible with Platform Manager devices are available on the Lattice website at http://www.latticesemi.com/products/powermanager/platformmanager/, including, among others, PWM Fan Control, Connecting an I2C Slave to SPI Master Bridge and a BSCAN1 Multiple Scan Port Addressable Buffer. Thirty-one additional design examples are also available from directly within PAC-Designer 6.1 software that provide instructions and solutions for Power Manager II and ispClock devices.

Third Party Design Tool Support The integrated PAC-Designer 6.1 and Lattice Diamond 1.3 software includes the Synopsys Synplify Pro advanced FPGA synthesis for Windows. Aldec's Active-HDL Lattice Edition II simulator is also included for Windows.

In addition to the tool support provided by the OEM versions of Synplify Pro and Active-HDL, Lattice devices are also supported by the full versions of Synopsys Synplify Pro and Aldec Active-HDL. Mentor Graphics ModelSim SE and Precision RTL synthesis also support Lattice devices.

About the Platform Manager Family

Named 2010 "Product of the Year" by Electronic Products magazine, the Platform Manager product family consists of two devices, the LPTM10-1247 and LPTM10-12107. The LPTM10-1247 device can monitor 12 voltage rails and supports 47 combined digital inputs and digital outputs, while the LPTM10-12107 monitors up to 12 voltage rails and supports 107 combined digital inputs and digital outputs. Functionally, these devices include both a power management section and a digital board management section. The power management section consists of a programmable threshold, precision differential input comparator block with an accuracy of 0.7%, a 48-macrocell CPLD, programmable hardware timers, a 10-bit analog to digital converter and a trim block for the trimming and margining of supplies. The digital board management section consists of a 640-LUT FPGA and programmable logic interface I/O.
