Integrating SystemVerilog and SCE-MI for Faster Emulation Speed

Wednesday, October 9th, 2013

In the last SCE-MI article, we discussed how SCE-MI macro-based infrastructures can speedup SoC design verification time. In SCE-MI 2.1, Accelera introduced a ‘function-based’ infrastructure which is based on SystemVerilog DPI functionality. The SystemVerilog DPI is an interface which can be used to connect SystemVerilog files with foreign languages (C, C++, SystemC, etc).

The WHAT is mandatory but the HOW is entirely optional

Monday, September 9th, 2013

You look confused. Perhaps I owe you an explanation. Anyone familiar with hardware design flow knows that it starts with specification and ends with implementation. The specification in this flow is the “What” – it defines what needs to be designed. The process for implementation is the “How” – it defines how you are going to achieve it.

Let’s break down just one part of the “How” or implementation – the Design Process. For many years hand-coded RTL has been used as the de facto method for implementation and it is still being used as predominant method for designing cutting-edge hardware. But does it follow that it is the most efficient method? I would say probably not, especially given the ever-growing complexity of the hardware.

The Magic of CyberWorkBench

Thursday, August 22nd, 2013

Dr. Benjamin Carrion Schafer, Assistant Professor at Hong Kong Polytechnic University (and longtime fan of Aldec’s latest offering, CyberworkBench from NEC) was kind enough to author a guest blog for Aldec. Here’s an excerpt:

My first encounter with NEC’s CyberWorkBench (CWB) was in 2003 while attending DAC. Like most people, I was surprised to see a big Japanese company offering EDA tools. NEC is definitely known more for its consumer products and telecommunication equipment. I have to admit, the main reason I stopped at their booth – was that they had hired a magician.

This magician told the audience he would teach us a trick and give us a set of magic cards if we stayed until the end of the presentation. I did and I received my set of magic cards (which I still keep). At the same time I also became a CWB user and even wound up working for NEC.

As an assistant Professor at the Hong Kong Polytechnic University, I currently teach advanced VLSI courses and use CWB. It has some amazing capabilities. Let’s start with the fact that it supports ANSI-C and SystemC. Although SystemC might be a step in the right direction to have a unique standardized IEEE language, supported by all main HLS tools, it is not very intuitive and takes some time to master (especially if the user does not have a C++ background). Here is where ANSI-C support becomes very handy. Most people do know ANSI-C and it is very straightforward to convert any ANSI-C SW description into synthesizable C code.

Wait….Did you say HDL Editor?

Monday, June 24th, 2013

Productivity Boosting Features
Yes I did, but with no intention to start a holy war on which HDL editor is best. When it comes to HDL editors, each engineer has their own choice and I am not attempting to hurt any madly, deeply felt sentiments. My goal is only to bring the awareness to those using the HDL editor built into Active-HDL™ and to help them use it more efficiently.

There are two main categories for HDL editors (1) general purpose text editors, and (2) integrated text editors. Both have their own pros and cons, and in the end it is for each engineer to decide which suits their needs.

The HDL editor built into Active-HDL falls under the second category of integrated text editors. It offers many basic features (syntax highlighting, templates, columns selection, code folding, auto-formatting) as well as semantic features (code navigation, on-the-fly error detector), and also offers seamless integration with the simulator and version control system. The HDL editor in Active-HDL can be used with VHDL, Verilog, SystemVerilog, SystemC, C/C++, PSL, OVA, Perl scripts and Tcl scripts.
