Study Notes
HDL Design Flow
- Synthesis is the final step in the HDL design flow before hardware testing.
- Synthesis translates the HDL description into a gate-level netlist, a representation of the circuit using logic gates.
HDL in Digital Design
- HDL (Hardware Description Language) is crucial for designing complex digital systems.
- It allows designers to model the behavior of the circuit using a high-level abstraction, simplifying the design process.
- HDL streamlines design, simulation, and verification, particularly in CMOS technology where complex circuits are common.
CMOS Transistors
- PMOS and NMOS transistors are essential building blocks for CMOS circuits.
- Unlike NMOS transistors that conduct when the gate terminal is high, PMOS transistors conduct when the gate terminal is low.
- This complimentary property of NMOS and PMOS transistors is fundamental to the operation of CMOS logic gates.
Role of Testbench/TINA
- Testbench or TINA (Testbench in HDL for Automated Verification) is a critical component of HDL design.
- It simulates the behaviour of the circuit under various input conditions.
- Verification using the testbench ensures the designed circuit meets the intended functionality before hardware implementation.
