Electronic Design.
From concept to your physical hardware.
Given a set of objectives and requirements, Tetra-H can produce a circuit capable of implementing your objectives. This will involve many decisions beyond the scope of this web page including cost, power requirements (including battery operation), compliance with standards, interfacing with other circuitry, software/hardware task allocation, size and fit, using hazardous voltages, compatibility, aesthetics, etc. For guidance, this is outlined in the following steps:
PCB design and manufacture: 〜 Using CAD tools to provide totally custom circuit design and PCB layout. Working closely with mechanical constraints and to relevant standards (such as EMC) this will also be to a PCB budget cost. The finished design can be passed to a manufacturing company, or Tetra-H can procure and supply boards to a prototype level. In all cases, the design will be explained and documented.
Analogue: 〜 The world is analogue, and interfacing with it will always involve analogue circuitry. Tetra-H can do this. Design of analogue interfaces is not unusual but can be fraught with unforeseen problems. Analogue design is far more susceptible to layout and external interference. In addition, for external measurements, sensors, or signals there are issues of impedance and aliasing; both for inputs and outputs.
Digital: 〜 There is often need for specific digital circuitry to enhance performance or deal with specific external features. These are often straightforward, but Tetra-H will be able to put together an optimal design avoiding potential problems.
FPGA design in HDL: 〜 Ultimately, there may be the need for extremely fast processing, which is better realised purely in digital hardware than in a microsystem. In this case, this will involve an FPGA or similar digital circuit capable of customisation and providing tens or hundreds of thousands of equivalent digital gates. Tetra-H can use a combination of techniques, resulting in hierarchical use of schematics and Hardware Description Languages.
