Pspice model errors in Virtuoso

Hi Guys

I am trying to simulate MAX9643U and EL7202 (using their Pspice models) as a part of my design, in Virtuoso. While I have reviewed many similar problems and solutions in this informative website, I still can not overcome the errors.

1) MAX9643U
(the model is available here:
www.maximintegrated.com/.../MAX9643U.LIB)

The problem points to the line:

Fi+ RS+ GND VALUE={-I(Vi+)+20.02u}

I read in one of the posts that I have replace {} by ''. but the error still exists and says:
"Expected 1 controlling voltage sources, but found 0"

2) EL7202
(the model is available here:
www.intersil.com/.../el7202.txt)

The problem (I guess) is related to the lines below:

.model spmod vswitch ron=3 roff=2meg von=1 voff=1.5
.model snmod vswitch ron=4 roff=2meg von=3 voff=2
e1 out vss table {(v(inp)-v(inm))*5000} = (0,0) (3.2,3.2)

and the error says:
"Error (CMI-2078): I1016.sn: Required parameter 'file' is missing"
"Error (CMI-2078): I1016.sp: Required parameter 'file' is missing"

Any comment is highly appreciated, in advance

If you are talking about PSS analysis (periodic steady state analysis), there is a way to calculate PAE (power added efficiency).
Article 1837740 Power Added Efficiency Calculation after PSS simulation
http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:ViewSolution;solutionNumber=1837740

There is an equation in this reference which shows the equation for efficiency, when defined as "The efficiency, η of the circuit is the proportion of all the energy dissipated in the circuit that is dissipated in the load." You can create a calculator expression for this.

As Andrew mentioned...there are different types of efficiency. A clearer problem description will likely give you better answers. :-)

best regards,
