Electric VLSI: "Getting Java Memory Limit Error" Solution

Could you not get your JAR files to run just by double-clicking them, or does the error - "Setting maximum permanent space blah blah blah to blah" repeatedly pop up in the command prompt when you call it?Unfortunately, I have fallen victim to the same problem while re-configuring the maximummemory limit of Electric VLSI, a freeware EDA developed by Mr. Steven Rubin.I've scoured forums and web pages in vain, then stumbled on a surprisingly simple answer below.Kudos to Mr. Jacob Baker and Kuangming for providing a quick and effective solution.On Wednesday, December 31, 2008 2:44:43 PM UTC, Jake wrote:> > Kuangming, > > Try this, > > In Windows click Start, Run, then type in the command prompt "regedit" > (Registry Editor) and navigate to the path by expanding the appropriate > sections:> HKEY_CURRENT_USER / Software / JavaSoft / Prefs / com / sun / electric > Deleting folder electric folder will start you off like you are run…

What If's: An Oscilloscope Trigger System in the Frequency Domain?

If you’ve tuned in on Electronic Design’s articles lately, you’ll know about a series by Mr. Colin Mattson on advanced oscilloscope triggering techniques. In the 1st article, he elucidates on pulse and pattern modes, where the characteristics of a pulse and the uniqueness of a pattern are utilized as the impetus of signal acquisition. In part 2, he delves into edge mode triggering, where the edge characteristics of a signal are used to mark the trigger for waveform capture. In part 3, he covers protocol triggering, where the patterns adhered to by a protocol (such as I2C and SPI) are detected. As of the time of writing, his readers still await his next article on sequence and software search triggering techniques.

A comment on one of his articles reads:
Email on trigger! I thought you were joking, but that’s an incredibly weird and fun capability. As someone who has spent a lot of time waiting for powerline transients to happen (or not), that’s a really nice idea.” – Ed Price

Ethical Considerations in Autonomous System Design

Technologies that operate without human intervention have been emerging spontaneously in diverse applications, from commercial transportation such as driverless cars, to military vehicles like remote-controlled tanks. Support is affluent from eager investors, who are perhaps looking forward to a similar market effect the IoT had. While an autonomous system [abbreviated AS for the rest of this article] has its perks of relegating tedious manual tasks towards a more comfortable lifestyle for consumers, they attract a lot of worry due to the freshness of the concept and the lack of a firm foundation in guaranteeing security. The risk of an unanticipated catastrophe is very real. There are still too few literatures that address questions on safety. Furthermore, fewer of those literatures that do address our qualms fall short of a satisfactory answer. In fact, Mr. Frenzel shares his refutations on autonomous vehicles in his blog posts.
