If you have predefined ranges and want to use specific colors for those ranges you can declare custom colormap. For example: import matplotlib.pyplot as plt import numpy as np import matplotlib.colors x = np.linspace(-2,2,500) y = np.linspace(-2,2,500) XX, YY = np.meshgrid(x, y) Z = np.sin(...

The concept of timing is related more to the physics of flip flops than VHDL, but is an important concept that any designer using VHDL to create hardware should know. When designing digital hardware, we are typically creating synchronous logic. This means our data travels from flip-flop to flip-flo...

Let's say you've got a table of loans, and another related table of parcels, where each loan can have one or more parcels associated with it.
