Reitityskäytäviä

Reitityskäytäviä, known in English as routing channels or routing conduits, are dedicated pathways within electronic design automation (EDA) tools used for the physical layout of integrated circuits. These channels are specifically designated areas on a chip's design where routing wires, which connect different circuit components, are allowed to pass. Their purpose is to manage and organize the complex web of interconnections, preventing them from crossing each other indiscriminately and causing signal interference or electrical shorts.

The implementation of reitityskäytäviä is a crucial step in the physical design phase of chip manufacturing. By pre-defining these channels, designers can guide the automated routing algorithms, ensuring a more efficient and reliable placement of wires. This helps to minimize routing congestion, reduce the overall chip area, and improve the electrical performance of the circuit by optimizing signal integrity and minimizing parasitic effects. Different types of reitityskäytäviä can be defined based on their width, routing density, and the types of signals they are intended to carry, such as power supply lines or high-speed data signals. The effective use of reitityskäytäviä contributes significantly to the successful fabrication of complex and high-performance microchips.
