IP provider steps up tool support for mixed-signal ASICs

July 14, 2015 // By Graham Prophet
Dolphin Integration has new releases of tools to support its mixed-signal front-end design offerings; there are upgraded versions of its SLED schematic editor along with the SMASH mixed-signal simulator.

SLED enables designers to graphically capture and configure their designs. The flexibility of the schematic editor SLED supports design of true mixed-signal circuits as well as multi-level and multi-physics systems.

For each process node and variant, foundries provide a Process Design Kit (PDK) containing all the files needed for front-end and back-end design. To assist in the integration of PDK files relevant for front-end design, SLED 2.4 has a PDK import feature enabling fast and easy generation of a SLED front-end PDK. SLED 2.4 also delivers ergonomic and ease of use enhancements to improve the overall user experience and productivity.

SMASH is a mixed-signal simulator with multi-language and multi-level simulation capabilities. Staying on the cutting edge of simulator performance, SMASH 6.4 offers three major steps forward:

Thanks to a new analogue solver, SMASH 6.4 shortens simulations of big analogue circuits from weeks to days. Loading of logic circuits is up to twice as fast as previously thanks to the integration of a new compiler. Speed is increased, and memory footprint reduced, under Linux with a native SMASH application.

SMASH 6.4 also delivers features such as “magnetizing” of waveforms for easy viewing of signal characteristics, continuing transient simulation even after the initial end time has been reached, as well as IDE enhancements to constantly improve the overall user experience and productivity.

“Magnetize” is a new command which allows obtaining exact values, driven by simulation results instead of graphic approximations. The exact values of the waveforms are displayed and differences, such as propagation or rise/fall times, can be easily measured.
