Clone PCI Slot Card Printed Circuit Board

Clone PCI Slot Card Printed Circuit Board

The first task of clone PCI Slot card Printed circuit board is to decide on the size of the board and on the number of layers.

In practice the form factor of the board is often predetermined or at least limited by the kind of device to be built, such as a PCI slot card, for example. The problems faced in the Printed circuit board clone process of VLSI circuits are in many aspects similar to those encountered on PCBs.

Again components (cells) are to be placed and have to be connected. Many algorithms can be applied in both cases. In fact, there are a lot more publications on the VLSI aspects of these problems than on their PCB counterparts.

 

 

On the other hand, many technical constraints in Printed circuit board clone are different from those in VLSI design. In this article, we focus on PCB based publications where possible.  Most of the articles dealing explicitly with PCB design describe a Clone Printed Wiring Board issue and a heuristic for its solution. The utilization of heuristics is not surprising, as the problems encountered in physical PCB layout are usually NP -hard in theory and computationally expensive in practice.

At this point, one particular feature should be noted: The vast majority of the nets to be routed between components has only two terminals. This property is an important reason why many of the heuristics used for routing (and described later) work quite well in practice despite their simplicity.

Regarding theoretical aspects there seems to be only limited progress in recent years. On the practical side, several commercial placement and routing software systems are purchasable. Assessing their quality is very difficult, as there are no generally accepted benchmarks for PCB placement and routing publicly available.

Clone PCI Slot Card Printed Circuit Board involves a large amount of technical and other constraints (collectively called design rules), which are specified and handled differently in each program, making any comparision difficult.
