Circuit Design.
Tetra-H designs cost-effective and compliant circuits.
Circuit design involves choosing an overall architecture and components to provide the necessary performance. It is not easy to cover this topic in a web page, but a number of basic core issues arise.
Apart from the obvious mechanical constraints and the need for particular inputs and outputs, there is often a tendency to either over-engineer a design or to miss aspects that might not be apparent at the outset.
In particular, in the case of a microprocessor-based design, the expected software overheads and processing speed requirements will often dictate the complexity of the circuit.
This is where many savings can be made by careful consideration of software overheads (e.g. an operating system or communications stack) and careful analysis of what the market has to offer.
It may be possible to build the circuit to do the required tasks with considerably less processing power than anticipated by implementing functionality at a lower level. In particular, for real-time systems. Reducing software overheads can also reduce system clock speeds.
Allowing the use of simpler double-sided or four-layer boards reducing costs and easing EMC, which along with other design standards need to be taken into account.
