As the importance and complexity of medical device software continues to increase there is growing demand for effective process assessment and improvement in this domain. To address this need the Medi SPICE process assessment and improvement model is being developed. Regulatory compliance is both an important and challenging aspect of medical device software development. Particularly as new reg...

The demand for medical device software continues to grow and there is an associated increase in its importance and complexity. This paper discusses medical device software process assessment and improvement. It outlines Medi SPICE, a software process assessment and improvement model which is being developed to meet the specific safety-critical and regulatory requirements of the medical device d...

A SPICE model for the microwave and RF PIN switching diode is presented. The model simulates the important Iregion charge storage phenomenon and its effect on the PIN diode impedance-frequency characteristic. The SPICE model is described and validated by comparisons with both analytical and measured results.

With single-electron tunneling (SET) technology it is possible to build electronic circuits with extreme low power properties. These SET circuits must therefore operate in the single electronics (current) regime. To simulate SET circuits in this regime, a SPICE (Simulation Program with Integrated Circuit Emphasis) model has been written In contrast to, the prescriptions in the so-called Orthodo...

This paper proposes a memristor SPICE model using the Tukey window (or tapered cosine window) function. Compared with the previously proposed models based on the boundary function, the proposed model is resistant to numerical errors. From the SPICE result of a relaxation oscillator, we observe that the proposed model can be effectively used to minimise the effect of round-off errors.

We are the rst to develop SPICE compatible circuit model for reluctance K It can be combined with any reluctance based extraction method to perform RLC simulation directly without the need of inverting reluctance matrix back into inductance domain or modifying conventional simulator To build symmetrical reluctance matrix we also proposed blocked K method based on group concept to cover more mag...

SPICE is a widely used tool for simulation of analog circuits. Accurate models of devices are crucial for obtaining realistic results from the simulation. Although SPICE provides circuit designers with built-in models for most widely used devices many devices still must be modelled with subcircuit models in order to achieve sufficient accuracy. The hardest part of creating a SPICE model for a p...

SPICE is a de-facto standard for free circuit simulation and the role model for most commercial simulators. In this paper we present the SPICE OPUS circuit simulator which is based on the SPICE3 source code. The shortcomings of the original SPICE3 and of its device models are highlighted. We present the solutions to these shortcomings that were implemented in SPICE OPUS. Three promising open-so...
