Improvements to Lattice Diamond and iCEcube2 tools accelerate design of low density FPGAs
1/24/2013 11:32 AM EST
Lattice Semiconductor Corporation has added an array of advancements to
its Lattice Diamond and iCEcube2 design tools, including improved power
calculations and design productivity.
Lattice Diamond 2.1
updated Diamond Power Calculator contains a matrix that displays the
power consumption of each block and each power supply. Also, the
detailed power analysis for multiple design implementations can now be
easily compared side by side in a new chart, extending the benefits of
design exploration. For power- aware FPGAs such as the Lattice MachXO2
device, designers, designers can view the detailed power analyses for
the two power modes side by side.
Diamond 2.1 software’s Hierarchy view is now automatically available
alongside the File List and Process views. It displays design resource
usage at various stages of the implementation process, and allows the
user to move directly to the HDL
source for each level of hierarchy, to designate any level of the
hierarchy as the top of the design, and to generate symbols for any
level of hierarchy. Verification and debug has also been upgraded.
The Reveal debugger now supports debug insertion into a mixed language design at the HDL level,
preserving buses and type information. The Simulation Wizard has new
options that allow users unfamiliar with simulators to easily start
simulations and trace signals.
The LatticeMico System’s
capability for generating system platforms has also been improved. Now,
designers can easily expand the peripheral set of their microcontroller
by connecting it to an FPGA that contains a peripheral-only platform
generated by the LatticeMico System.
Ultra-Low Density FPGA Design Software for iCE40
software is the design environment for the Lattice iCE40 family of
ultra-low density FPGA devices. The updated iCEcube2 software includes
improvements that increase accuracy. For example, the new version of
iCEcube2 software now includes final timing and power data that enable
design analysis under worst case as well as typical conditions. The
updated data also reflect wider temperature ranges to support both
commercial and industrial devices, which gives designers greater
confidence that their design will operate correctly in a variety of
conditions. The power estimator also has improved data and algorithms
that increase the accuracy of dynamic and static power calculations.
software for Windows Operating System can be downloaded from the
Lattice website, and is fully enabled at no cost with the Lattice
Diamond free license. More information
