Analog and Mixed Signal Design
Conversion and translation of electronic signals from one format to another is a key function for getting disparate systems to communicate. The external environment is analog, so sensor input signals are converted to digital format for storage, manipulation, and transmission. They are then converted back to analog to drive heaters, motors, displays, antennas, and speakers. Some analog signals are more easily converted first in the analog domain prior to digitizing, such as RMS and energy measurement. For ease of transmission, digitizing can also be done to a proportional frequency with a V-F converter.
The class will present several typical design flows including second-order effects: power estimation and low-power design (both at high level and at gate level) and speed optimization for digital circuits; process variations and mismatching effects for analog circuits; signal integrity issues and complex simulation for mixed-signal circuits and design and simulation of RF-ICs.
A break statement is embedded in the sequential logic of a conventional VHDL process and so executes at a particular time. The break statement signals a discontinuity at that time by scheduling a zero-delayed transaction on the implicit break signal. It can also specify new initial conditions for selected quantities. The implicit break signal cannot be referred to directly by the model because it does not have a defined name. Its value is in any case of no interest -- only the fact that its driver is active is interesting.the digital signal processing (DSP) core of a system and the analog world. The processing of signals is predominantly performed in the digital world rather than in the analog world. This is because digital circuits can achieve tremendo
