Calibration on ADC - Calculations are all correct - but plotting doesn't work on sweeps?!

Hello,

I am trying to do a calibration of an ADC using the calculator functions. I keep getting issues with unbound variables from my calibration calculations.

Steps that I am using (roughly sketched, do a bunch of similar calculations):

1) create digital word bus using:

awvCreateBus("code_out" list(awvAnalog2Digital(VT("/code_x<9>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<8>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<7>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<6>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<5>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<4>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<3>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<2>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<1>") nil nil 0.5 nil "centre") awvAnalog2Digital(VT("/code_x<0>") nil nil 0.5 nil "centre")) "Unsigned Decimal")

2)

Then I use a cross statement to get a time value - I use || operator to get 0 if crossing statement fails.

3)

I had some issue with extracting the word at the time but ended up with:

atoi(awvGetScalarFromWave(value(code_out t_v1_calib_sample)))

4)

Then I do some calculations and then I multiply a gain and offset to a wave where I converted the digital code to a an analog waveform using:

code_out_V = clip(awvDigital2Analog(code_out 4.7 0 0 ?mode "busvalue") t_conv_done VAR("simtime"))
code_out_V_corr = ((code_out_V_sample * g_calib) + o_calib)

Now the issue:

When running a single point simulation this works very well - however when running sweeps I can no longer plot my code_out_V_corr ? It fails saying that a bunch of variables are unbound.
