What is the importance of a good floor plan in analog layout design?
A good floor plan is important to the construction of an analog layout because it ensures that the circuit’s various building blocks are positioned to reduce interference and noise. By ensuring that vital signals are efficiently routed and that the distribution of power and ground is maximized, a well-thought-out floor layout can also aid in enhancing the circuit’s performance.
When creating a functional floor plan for an analog circuit, there are several things to take into account. They consist of the following:
Signal integrity: To reduce noise and increase signal integrity, the floorplan should be created to reduce the length and quantity of vias (interconnects) of key signals.
Testability: By making test points and debug signals easily accessible, the floor plan should be created to make it easier to test and debug the circuit.
