Recently I posted about the challenges of using a write only port. Then I followed that up with another posting that illustrated the use of C++ to encapsulate the necessary coding nastiness. Hopefully, these two postings conveyed the general ideas – defining the problem and outlining a solution. However, one aspect of the solution was not addressed: the proposed code was not reentrant … Reentrancy … Read More

I recently wrote about write-only ports and discussed how they worked and the challenges presented to software developers who need to program them. The solutions proposed were quite straightforward, but the challenge remained to ensure that all the code utilizing the ports complied with the requirements. I commented at the time that there are several ways to mandate the correct handing of write-only … Read More

I often joke that my job puts me in a difficult position, as I am a software guy and a very large proportion of Mentor Graphics employees are hardware design specialists; I am consorting with the “the enemy”. Although I am making a light-hearted comment, there is, sadly, something of an “us and them” attitude between software and hardware teams in many companies. It is in everybody’s … Read More

Welcome to part two of my four-part (part one) ESC 2010 blog series. Today’s topic: shifts in the industry. One of the biggest trends I observed at the show was the start of a paradigm shift in the evolution of Electronic Design Automation (EDA) software companies and their products. EDA software companies have traditionally provided the software tools and services to create modern day semiconductors, … Read More
