Detailed Technical Solution & Explanation
In VLSI and electronic system-level (ESL) design hierarchy:
1. Algorithmic / System Level: Implements high-level algorithms (e.g., in MATLAB, C/C++, SystemC) validating mathematical correctness and logic flow without concern for clock cycles, registers, or hardware architecture.
2. RTL (Register-Transfer Level): Defines cycle-accurate register transfers.
3. Gate Level: Describes interconnected logic gates.
4. Switch / Circuit Level: SPICE transistor-level analog simulations.
