Hi!
In the early 2000s I worked on PCBs for an Aircraft to Ground telephone communication system for a former employer, using a British design package called Electronic Design Studio.
It wasn't cheap (over £1000) for all options, and came with a "key disk", supplied on floppy to licence it, and it checked the floppy each time you started it, and I made more calls to their technical support over problems from this "key disk" than any other issue!
Eventually after several years worth of complaints I got them to change it to a Serial Number activated system, but even that was notoriously unreliable as well!
One morning I logged onto the website to be greeted with one line of text:–
"The website is under new development and we hope to be back shortly"
A month or two after that, I asked our friendly RS Rep if he could tell me any more, and he said "the Manufacturers have gone bust – we've had to stop selling it and destroy our remaining stock of this software because we cannot support it!!"
During the time the publisher was in business, I asked if there was any means of backing up the licensing key but they refused point blank to help with this!
Whatever licence method EDS used, it certainly seemed to be effective as no "cracked" version ever came to light!
When the employer closed the Electronics Department ten years ago, they gave me the "Easy PC" licence they no longer needed, and the girl at Number One was happy for me to continue to use it to buy a V24 Upgrade just before Christmas – that's how this software should be licenced – fairly priced and no compulsory subscription nonsense, insistence on your design files becoming "their" property (Are you listening Altium?), or reliance on "dongles", "key disks" or "activation".
So yes, there is a well–priced "perpetual licenced" EDA product – try "Easy PC" or "Design Spark Pro" from RS – (Design Spark Pro is about 15% cheaper @ £375 plus VAT)) and there are no silly pin limits in the full version (Easy PC does offer much cheaper 500/1000/2000 pin count versions if you're only needing to make very small hobby designs).
The autorouter in Design Spark Free is pants, but Easy PC had absolutely no problem with my friend's board using it's free "Trace Router" – DSPCB free couldn't do it full stop!
