AI Thread Summary
Users express frustration with the LASI software, finding the introductory materials insufficient for practical applications, particularly in drawing CMOS or resistance layouts. They note that tutorials focus on basic functions rather than providing comprehensive guidance or examples. Questions arise about the relationship between LASI and MOSIS standards, with uncertainty on how to apply these standards in practice. Recommendations include consulting a good CMOS layout book and seeking assistance from experienced colleagues. Despite its limitations, LASI remains a valuable freeware tool for layout design.

I read through the LASI introduction once and also watched the teach-how video in Youtube, but feels really frustrated about this software...

all these introductions only show how to "draw a box", "draw a polygon", "how to add", "how to move" and this kind of basic kindergarten skills. What does it actually means? Does it means those are all I need to know for using the LASI software? I don't even know how to start a drawing for a CMOS or a simple Resistance! Not a single practical drawing example I can found on the internet!

and by the way, what is the thing MOSIS do with LASI? do I supposed to follow the MOSIS standard to draw with LASI? but how...?

Thanks for all your helps!

Get a good CMOS layout book and get help from seniors to learn how to draw chip layout.
e.g. IC Layout Basics : A Practical Guide [Christopher Saint, Judy Saint]

LASI is little old tool for drawing layout and it might be a bit painful to work in it. Still it is probably only freeware Layout tool that is good enough.
 
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
