SimulIDE 1.0.0 Tester builds.

Is it possible to get an "intermediate tester version"?

Yes, I plan to upload it today.

There are some last minute bug reports.
I will try to fix as much as I can and upload later today.

Diak doesn't work. At the breakdown voltage, the program freezes.

New build at Rev 956 uploaded.

Have a look at first post for download links and list of changes.

Had no time to solve this one.
I will have a look.

Solved at Rev 958.

Another problem with PIC16F886.
I checked the operation of the controller circuit of the tape drive mechanism of the tape recorder (see the post https://simulide.forumotion.com/t390p75-simulide-1-0-0-tester-builds#2566 ) and found errors. I conducted several experiments with the scheme and got the following results:
1. The original scheme after running the simulation leads to the crash of the program. I found the reason. It turned out to be quite unusual. To eliminate the crash of the program, you need to get rid of one of two problems (there are no such problems in the R941 version!):
№1. Change the properties of the seven-segment indicator (reduce the forward voltage to 2.4 V. and increase the resistance to 100 ohms).


№2. The problem with the 74HC00 chip. The model is made on 3 NAND logic elements and one function:

If you replace the inverter from this chip [1A 1B - 1Y] with a conventional inverter, then the program does not break at start.


The program freezes if the circuit consists of only the specified two components:



2. The microcontroller model contains an error. I used the debug mode and found that the simulation stops at 181 lines of the program (waiting for the button to be released).


The archive contains the original scheme and a new scheme with corrected indicators and additional buttons for debugging the program.

I hope that the information will be useful to eliminate errors.

Thanks for the detailed report.

I can't reproduce this problem, maybe it's already solved.

Problem in Function solved at Rev 967.

But I'm curious... why is a function and not another NAND gate?

The microcontroller model contains an error. I used the debug mode and found that the simulation stops at 181 lines of the program (waiting for the button to be released).

This was because a problem with internal pullups.
Solved at Rev 964.

But I'm curious... why is a function and not another NAND gate?

I think I did this when I discovered errors in the simulation of functions. I forgot to put the NAND valve back in place. It is better to remove the function from the model.

Well... it was useful to find another error.

It is better to remove the function from the model.

Ok I will do.

SCR doesn't work

SCR doesn't work

Thanks. Hopefully solved at Rev 996.

The diode does not work correctly

The zener diode does not work correctly

The diode does not work correctly

Solved at Rev 1000.

The zener diode does not work correctly

This one is not so easy.
I'm investigating it.

The "Function" component does not work in analog mode: when the input voltage changes, the output voltage does not change. After restarting the simulation, the output voltage corresponds to the formula.

Thanks.
The "Function" component always has something else to solve...  

Solved at Rev 1001.

The zener diode does not work correctly

Finally solved at Rev 1006.

Now I can do the public relesase SimulIDE 1.0.0-RC2.

Not a critical error.
When the Show option is activated on new components, the label appears inside the component border, and they have to be shifted outside this border. The KY040 component has a label rotated 90 degrees.

user fifan  discovered a bug in the program when simulating the PIC16F877 microcontroller:

http://kazus.ru/forums/showthread.php?t=117173&page=79#785

I found a bug in the program. The ADDWF F, D instruction of the PIC16F877 microcontroller does not work at all. The register involved in this instruction does not change in any way in the two variants of this operand. In theory, the register a should be combined with the accumulator w and the result should be placed in the same register or in w.

The ADDWF F, D instruction of the PIC16F877 microcontroller does not work at all.

ADDWF is working correctly in both variants, the problem must be other.
The only reason that comes to my mind is a wrong baksel.

By the way...
Tunnels in this circuit are doing nothig:
