LONDON Three computer aided design tools that make up the Cascade package out of Columbia University are available for download, according to discussions in an asynchronous logic newsletter.
The three tools Minimalist, ATN-Opt and DES analyzer are available for download from the Cascade web page: http://www1.cs.columbia.edu/~nowick/asynctools/.
Each tool includes a tutorial, examples, and instructions on installation and set-up, but the tools are designed only to operate on Linux platforms.
Minimalist 2.0 is intended for the design of asynchronous burst-mode controllers and this version of the tool, with Verilog support, adds a multi-level optimizer package, improved graphical interfaces, auto-insertion of initialization circuitry, support for decomposition of specifications, and a top-to-bottom verifier.
ATN-Opt is a CAD package for the synthesis and optimization of asynchronous threshold networks. The package supports Verilog/VHDL/BLIF circuit formats, and the GENLIB technology library format. It allows the user to target various costs: delay, area, power.
The package can typically synthesize and optimize circuits of several thousand gates in several seconds, often with 30 to 50 percent improvement in area and delay over a direct-mapped implementation.
The discrete event system, analyzer is a performance analysis and timing verification tool for concurrent digital systems. The evaluation considers all extremes of behavior between a pair of events during the evolution of the system's behavior, from the initial state through 'ramp-up' phase to 'steady-state' behavior. This information provides bounds on minimum and maximum throughput, information on impossible orderings of events (useful for optimization), and other useful metrics.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.

In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
