In SoC (System-on-Chip) design, clock design is a core and highly challenging task that directly affects the chip’s performance, power consumption, reliability, and testability. A robust SoC clock architecture needs to consider multiple factors. Core Objectives. Functional Correctness: Ensure all modules operate on the correct clock edge, meeting timing constraints. High Performance: Provide clock frequencies … Read more
For general-purpose MCU chips, the CPU operating frequency ranges from 100 to 300 MHz, while the frequency of typical crystals (xtals) is usually in the tens of MHz range. Therefore, MCUs typically use a PLL module to multiply the frequency to the hundreds of MHz range.Similarly, taking the STM32F10xxx series as an example, let’s examine … Read more
Clock Design Solutions In complex FPGA designs, creating a clocking solution is a challenging task. Designers need to have a good grasp of the clock resources available in the target device and their limitations, understand the trade-offs between different design techniques, and possess a solid knowledge of a range of design practices. Incorrect designs or … Read more
