The thermometer code (also named as unary code) is useful to extract a vector number and use it to drive several switches. The thermometer code converts a n-bit number into a series of ones followed by zeroes of size 2^n.
Monte Carlo analysis is a statistical way to analyze a circuit. This simulation allows us to test the process variation and mismatching between devices in a single chip or wafer.
As a default Cadence has a non-user friendly text editor, but to code, we need to use another one like gedit. gedit is a small and lightweight text editor that allow you to highlight the text.
Real silicon circuits on the dies after the manufacturing process are unfortunately far from behave as an ideal circuit designed on Cadence. This allows do more realistic simulation at the by updating your circuit into a more realistic one based on the physical layout. In this way it is ensured proper functionality of the design and a better representation of the final silicon product behavior.
What are the most useful keyboard shortcuts in Cadence? With these keybinds, you will take advantage of the comlpex Cadence tool.
This VHDL-AMS block is an ideal comparator, which check if the actual voltage in the input pins above the given threshold is or not. The output is a digital std_logic signal named “result”.
