 Alan:
My coding skills are very very low, but if you have some simple task to me,
i can try....

About the pic simulation:

The create the "clock Mhz" property is solved, now i can select clock speed
and it works well; i have some extrange random behaivors, but the general
idea works.

About the analog input issue, i think i'm aproaching... i can send a fixed
voltage to gpsim and it works, but i have problems to take the node voltage.
I tried this (ktl.0.3.7):

_____________________________________________________________

piccomponentpi.cpp:
-----------------------------------------------------------------------------------------------------------
#include "ecnode.h"
#include "pin.h"

PICComponentPin::PICComponentPin( PICComponent * picComponent, PicPin picPin
)
    : m_id( picPin.pinID )
{
......
......
        case PicPin::type_bidir:
        {
            m_realNode = picComponent->ecNodeWithID(picPin.pinID);
            m_pLogicOut = picComponent->createLogicOut(m_realNode, false );
........
........

void PICComponentPin::logicCallback( bool state )
{
.......
.......
Vth = 3.3
.......
-----------------------------------------------------------------------------------------------------------


piccomponentpi.h:
-----------------------------------------------------------------------------------------------------------
    protected:
......
        ECNode *m_realNode;
-----------------------------------------------------------------------------------------------------------
_____________________________________________________________

This works well, pic takes 3.3 V as analog input and i can use this input
with an adc-read in the pic program.


but if i do this:
Vth = m_realNode->pin()->voltage();

Ktl crashes at startup ( with the last document a circuit with pic)

I also tried this:
_____________________________________________________________

piccomponentpi.cpp:
-----------------------------------------------------------------------------------------------------------
......

void PICComponentPin::logicCallback( bool state )
{
.....
Vth = Vpin
.....

void PICComponentPin::stepNonLogic()
{
    Vpin = m_realNode->pin()->voltage();
}
-----------------------------------------------------------------------------------------------------------

piccomponentpi.h:
-----------------------------------------------------------------------------------------------------------

public:
......
        virtual void stepNonLogic();
        virtual bool doesStepNonLogic() const { return true; }
......
.....
    protected:
......
        double Vpin;
        ECNode *m_realNode;
......

-----------------------------------------------------------------------------------------------------------

This doesnt work at all, looks like Vpin is never updated.

I see that all logic will be changed and it will work in a diferent way, I
just try to understand.
And i think it should work in ktl 0.3.7 and adapted to the new logic.

Do you think i should wait for the new logic is working?
