Technology
Overview
Tiempo offers a technology for the design of asynchronous and delay insensitive integrated circuits
- Tiempo asynchronous circuits are fully clockless, meaning that they are self-controlled and their behavior is governed by signal transition handshakes and signal levels memorization
- Because the circuits do not rely on a knowledge of timing, functional correctness is ensured regardless of any actual delay through gates and wires. This makes Tiempo’s circuits very resistant to perturbations that traditionally impact timing, such as the manufacturing process, or changes in voltage or temperature
- Tiempo implementation allows designs with both ultra-low power and high performances
- Tiempo technology can be described with high-level models, in standard language and implemented using an optimized high-level synthesis tool from Tiempo, called Asynchronous Circuit Compiler (ACC). The tool accepts as input SystemVerilog models and generates an optimized Verilog gate-level netlist.
