Each system needs to communicate with one or other system/peripherals. This chapter also discusses on the key design challenges in the multiple clock domain designs and even this chapter focuses on the design guidelines to describe the efficient clock domain designs. Multiple asynchronous clock domains have been using for different I/O interface in today's modern system on chip (SoC). The unit converts many kinds of clock signals into others, drives a Sync plugin via DAW, and is capable of acting as a master clock source. The chapter key highlights are the detail description for the synchronizers, data path, and control path synchronization logic using the efficient Verilog RTL. The E-RM Multiclock is a multifarious sync solution and interface designed as a one-stop-shop for the synchronization of compatible audio devices. Each high frequency clock that is independently generated forms a domain, and may be skewed from othe. This chapter focuses in the key design techniques which are used to describe the multiple clock domain designs while passing data from one of the clock domain to other. Answer (1 of 5): Board-level reference clocks generally go at a MHz speeds, but internal chip frequencies are much higher (GHz), and are often generated from the board level reference using PLLs. In this paper, We present the design of 5 types of CDC schemes in our developed SOC chip with multi working mode and ten clock domain, deeply describe an approach using assertion-based verification. Modern SoC employ multi clock domains on the same die, this is because each block of the system may require different clock voltage and frequencies which. The performance of clock synchronization directly determines the comprehensive performance of distributed cooperative systems such as multi-base radar detection and smart grid. These kinds of designs need to be described using the efficient design architectures and Verilog RTL. Clock synchronization is the basic service of information communication and the related research has been in the ascendant. synchronization failure occurs.' Figure 1 shows a synchronization failure that occurs when a signal generated in one clock domain is sampled too close to the rising edge of a clock signal from a second clock domain. In the practical ASIC and SOC designs the multiple clocks are used and the designs are called as multiple clock domain designs.
