500 companies download datatypes
Mentor Graphics' Algorithmic C (AC) datatypes enable algorithm, system and hardware designers to precisely model bit-true behaviour in C++ specifications while accelerating simulation speeds.
Mentor Graphics Corporation has announced that more than 500 companies and organisations have downloaded its Algorithmic C (AC) datatypes Originally announced in June 2006, AC datatypes are arbitrary-bit-width datatypes based on ANSI C++

Mentor Graphics and UMC deliver IC design kits
Mentor Graphics and UMC have joined to deliver a complete turnkey design flow, including the availability of IC design kits, for UMC's RF and analogue/mixed-signal process technologies.
Mentor supports TI DSPs and MCUs
Mentor Graphics is the first to reach agreement with Texas Instruments to deliver coverification processor support packages (PSPs) for Texas Instruments DSP and microcontroller solutions.
They enable algorithm, system and hardware designers to precisely model bit-true behaviour in C++ specifications while accelerating simulation speeds by 10-200x faster versus alternative datatypes.
More than 500 companies and organisations worldwide have downloaded AC Datatypes for free from the Mentor Graphics website.
This includes individuals from leading electronics companies, R and D organisations, academic institutions, government agencies, and electronic design automation (EDA) tool vendors.
AC datatypes reduce many of the compromises inherent in previous datatypes.
In terms of precision and performance, AC datatypes offer the best of both worlds: the ability to specify arbitrary bit widths, while improving simulation performance by 10-200x versus other datatypes such as SystemC.
AC datatypes also solve problems of semantic consistency associated with other datatypes.
The semantics of AC datatypes are intuitive and consistent, enabling designers to become proficient in just one day.
In contrast, there are semantic differences between limited precision SystemC datatypes and the arbitrary precision datatypes.
In reality, proficiency in one SystemC datatype does not ensure familiarity with the others, making it error prone to adjust bit width in a given design.
The AC datatypes have been designed to be easily used with ANSI C++ or SystemC design flows.
"Facilitating rapid progress from design concept to implementation is the core value proposition of electronic system level (ESL) design", said Shawn McCloud, high-level synthesis product line director, Design Creation and Synthesis Division, Mentor Graphics.
"In the algorithmic space, the free AC datatypes from Mentor Graphics increase designer productivity while enabling even greater control over design intent, all in a language that designers already know and trust".
"We are very happy that designers are embracing this approach and are surprised to see how quickly the new datatype is being adopted".
