As a world leading pure-play foundry, UMC offers comprehensive design resources that support our cutting-edge process technologies. Silicon verified libraries (standard cells and I/Os) optimized to our technologies are available free-of-charge from several leading vendors. UMC has also worked internally and with third party partners to deliver an extensive portfolio of IP that are optimized for portability and cost. These range from fundamental IP such as cell and I/O libraries to more complex processor and application-specific standard cores. And, because silicon verification is such a critical issue for customers' deep sub-micron designs, UMC has launched the Silicon Shuttle multi-chip test wafer program. UMC also makes available SRAM memory compilers to support all of its mainstream processes.
