Open Source FEM There is some pretty amazing open source software available for multi-physics FEM. This blog describes the open source software pulled together to perform FEM (finite element modeling). Originally I used QuickField, student version. However, the limitation on that software is that it is 2D asymmetric or planar with a 250 node limit […]

I am fascinated with feedback control systems. They always grab my interest. I’m in awe of the way something in the physical world can be expressed by a few simple equations. This is true for something as simple as a device failing by overheating because of a positive feedback loop. The temperature rise of an actuator

What’s Wrong with MTBF The use of MTBF (Mean Time Between Failures) is almost always applied wrong. As a producer of a product you would want the product to last beyond the warranty period and long enough to be perceived by the customer as a ‘Quality’ product. One way of quantifying this is that a

Fractional Divider This design note shows the derivation of the equation for a fractional divider (FD) and provides the verilog code implementation. This code has been tested to work on a Spartan 3AN and is available on Bitbucket. A fractional divider gives higher resolution in a digital PLL without increasing the clock frequency. As example,
