EDD model error: Operation expected in given equation

[ANUJ RAJPOOT]

• I have defined my device assigning the current equations in EDD model. When I am trying to execute the simulation, it is showing error “Error in ‘OFET’: Operation expected in equation “(Vds>0)?((Vgs-Vt0)>0)?0.5*beta*(abs(Vt0)^n)(abs(((abs(Vgs)/abs(Vt0))-1))^n)*tanh((alpha*Vds)/(Vgs-Vt0)):0:0″.”
• Help me out to rectify this error.

Hi, I don’t know if you manage to find a solution since last year, but I saw your post because I’m face to a similar issue:

I still work on QucsStudio 4.2.2

I had the following equation:

StabFactorK_less1= min(range(rollet(), 50MHz, 600MHz)) -1

The equation seems to be correct but a “Operation expected in equation” error occurs. My workaround is to split the equation with the following lines:

StabFactorK_rollet=rollet()

StabFactorK_less1= min(range(StabFactorK_rollet, 50MHz, 600MHz)) -1

 

Maybe someone else had the same issue ? it may be a bug ?

I will re-test that with the lates t QucsStudio revision as soon as possible.
