| May 21 at 0:08 | comment | added | Boldumus | I had been struggling with another similar software, Microcap12, because I couldn't specify the parameters for the A1 chip. On LTspice, I was able to copy your arguments and recreate your simulation (Vhigh=9, tripdt=10n, Vt=4.25, Vh=1.75, Td=70n, Trise=50n, Tfall=50n), and it worked like a charm. Could you give me a short explanation of what they represent? I know Vhigh is high output, but I'm unsure about the rest. I have trouble associating the names with the parameters from the datasheet. | |
| May 20 at 20:55 | comment | added | Fabio Barone | Interesting situation. The simulator I used is LTspice, it is available as a free download from Analog Devices website. You are welcome to try and enter the schematic and try to simulate the circuit yourself, let me know how you go. | |
| May 20 at 16:51 | comment | added | Boldumus | Given that, do you believe it would be possible for you to share the first simulation you did with me. I think it is entirely sufficient in quality and yelds close enough results that it would be suited for me to present to my teacher. I would of course explain to him that it was a task I was not qualified to perform and would reference this page as a source for the simulation in my report. | |
| May 20 at 16:47 | comment | added | Boldumus | I think that instead of wanting me to spend a huge amount of time learning how to simulate the circuit, the teacher mostly wanted to see a simulation of the circuit (as it's much easier to understand). Given that he is an astrophysicist by training but still teaches an electrical physics class and directs a variety of physics student projects, I believe that the first simulation you made is likely close enough for my teacher to understand the circuit. | |
| May 20 at 16:39 | comment | added | Boldumus | I think it is easy to figure he mostly was looking for something on which he could evaluate us, rather than really wanting us to learn an entire program or change our entire circuit's design to make simulating even possible. Your answer has given me insight into the world of circuit simulation, and I think the easiest course of action for me will be to explain to my teacher why simulating the circuit represented a challenge I was not equipped to deal with, or that it would require too much time to make sense in an 80-hour project (a time estimate I have already exceeded). | |
| May 20 at 16:30 | comment | added | Boldumus | Thank you very much for all the help, and especially for the effort you put into creating a comprehensive and clear answer to my somewhat confused question. Reading your answer, I realized that providing more context about my situation could have saved you some work. Sorry about that. First of all, context: this project is for a physics class, not even an electrical physics class. The teacher doesn't really have the qualifications to help me with this project, so it was a bit of a shot in the dark when he asked us to simulate the circuit. | |

Improved clarity: Added headings, line breaks.
