Controlled Voltage Source

Think I got a basic code working for a controlled voltage source. To begin with here is the code for the class (click on "view raw" below the code box to see the code in a new window):


The only difference between a normal voltage source is that it has two lists control_tag and control_values. The control tag is the name of the control input and the corresponding index in the other list is its value. These are lists because there can be multiple control inputs to any controllable device.

Next in the main program "circuit_solver.py". The first stage is to get the names of the control codes from the user. Then generate "descriptor" files for each of these control codes. Check if they exist. If they don't create blank templates (check the previous blog entry). This is the code (click on "view raw" below the code box to see it in a new window):


The next step is to take in the descriptor parameters. These will be used to update the dictionaries for the inputs, outputs, staticvariables and time events. Here is the code (click on "view raw" below the code box to see it in a new window):


The next step was a bit tricky. The idea is to write all these different control codes into one main program called __control.py and import this file. Each control code will be written as a function.

So basically, define the function, assign the input to variables, assign the static variables to local variables, assign the time events to local variables. And then finally embed the control code. Then assign the local variables to outputs, reassign local variables to static variables and time events as applicable to take these back to the main program.

Anyway, a basic circuit with a controlled voltage source works. So I'll just release this as the next minor version.
