| Background and Objectives: The automobile industry is becoming more technologically advanced. Modern vehicles are expensive, but they have cutting-edge security features. As a result, the average individual who can afford low-end vehicles must forego the latest improvements, such as greater safety. Therefore, the main goal was to create a small Internet of Things device that could be used on a mobile device to notify the user when a car comes from the opposite direction. It will promote human safety by alerting users to that vehicle. The preparation, integration, and deployment of a modern IoT-based vehicle detection device have been described in this work. From there, it goes through the OpenROAD toolchain, and OpenSTA is used for static timing analysis (STA) and the ASAP7 PDK is used for the design. In this paper, provide a performance evaluation study across all three metrics (power, performance and area), as well as the entire design flow from hardware description to final implementation. Methods: The entire behavioral level code goes through several stages before reaching a physical perspective, where various tools are used for multiple tasks. To obtain the desired physical-level architecture, first, use a tool to obtain the netlist file, including every G-cell map with a PDK-specific gate-level representation. Then, several stages will be followed to get the device’s physical view. Results: Throughout the entire experiment, the transition from RTL to GDSII was successfully achieved. Once the complete design is finished, the area, power, and timings all appear fine. Another unique characteristic is that the chip employed 7nm technology. The 5 GHz frequency was attained when the chip functioned flawlessly without DRC or any connection problems, timing, or DRV violations. Less than 1 percent is the maximum allowable IR loss maintained. Over 80% of the total space was utilized effectively. Conclusion: To build an IoT gadget manufacturable with the best PPA, the general experiment was to write RTL code and proceed to the tap-out stage. The experiment achieved the best result by utilizing open-source chip design tools. Additionally, there are no DRC violations, timing problems, or power loss. | ||
