Abstract [en]

Avionics Division of Saab AB develops advanced electronics that need to be

robust and work in harsh environments with for example extreme temperatures

and cosmic radiation without any failure. To succeed with this the electronics

need to be simulated and tested. Therefore this thesis work is done to

strengthen the Avionics Division’s knowledge of hardware modelling and

simulation by evaluating the simulation tools LTSpice, PSpice and

SystemVision, their functions and capabilities.

In this thesis a survey is carried out with help of a questionnaire to study the

Avionics Division’s needs for simulation. The survey is underlying an analysis

of the analyses that can be performed by the simulation tools for example

Sensitivity analysis, Worst Case analysis, Monte Carlo analysis and Parametric

Sweep analysis. The different analyses are discussed in the thesis. The

questionnaire is also underlying an analysis of the tools LTSpice, PSpice and

SystemVision. The result of the analysis is summarized in Table 1.

A case study of a circuit simulation in SystemVision, based on an existing

circuit used by Avionics Division, is also done within this thesis work. The

study is done to evaluate the tool’s usability, to see if it is easy to perform a

simulation and if it is easy to find and use suitable models from the model

library.

The case study describes how a simulation is performed in SystemVision and

how an AC analysis of a Butterworth filter is done. A stability and reliability

check of the tool is performed as well as a robustness simulation. The analyses

were easy to do and the overall impression is that SystemVision is reliable and

user friendly structured. In order to check and compare the results of the AC

analysis the same analysis is performed using LTSpice. The comparison shows

that the results differ. This depending on that the models of the circuit were

some what different in LTSpice and SystemVision.

The final conclusion is that SystemVision would fit within Avionics Division’s

workflow. Using SystemVision demands education of the engineers to secure

maximum use of all the advantages of SystemVision.
