Hi,
I'm trying to do a really simple sim just to get started. I've searched help, forums etc but I'm pretty stumped why this simple example is not working. So any help / suggestions would be greatly appreciated.
AC voltage source feeding a simple divider of 2 x 1K resistors. I've added a GND component too, as described in tutorials, to the bottom of the divider. I took the components from the spice lib.
The circuit is like this...
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\| \| \-\-\-\-\-\-\-\-\-\-\-\-\-Voltage Probe 2
\| R1 1K
Supply \|\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-Voltage Probe 1
SIN(0 1 1000 10m 1 0) R2 1K
\| \|
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\|
GND
1\. I started on desktop version\. The sim runs OK\, and I can see the sim report\. But no waveform window opens\.
2\. So I moved to the web version\. This time I got the waveform window\. But no AC at the probes\. Probe 1 was constant 0\.5V\, probe 2 constant 1V \(so it sims the divider OK but somehow the AC voltage source is operating as DC 1V\)
3\. Then after a number of retries\, forum searches etc the waveform window stopped opening after the sim run in the web version too\. Again the sim runs without error\, just no waveform window
4\. So now whether I use desktop or web I get no waveform window after the sim runs
So I guess I have two main questions
\- Why is the waveform window not displaying even after successful sim run?
\- When it did show\, why am I getting flat DC from an AC source?
I'm happy to share the project but on trying it went to publish to the OS HW platform (I wasn't sure I should clutter this with my simple test). I did in the end try but it gave an error (flashed up briefly in red text but had no time to read it).
This is the netlist download after the sim run...
