The process of prototyping and validating ASIC using FPGA reference:http://xilinx.eetrend.com/d6-xilinx/article/2018-10/13736.htmlGiven the complexity of chip design, the steps and processes involved in successfully designing a chip are becoming more complex, and the amount of money required is multiplied, and the cycle and cost of a typical chip development project is as follows
Can be seen before the chip manufacturing, a lot of energy will be
Network Foundation to Promote the Software Defined Network implemented by OpenFlow. These large companies agree with other supporters that OpenFlow is particularly useful for load balancing, traffic control, and virtual networks in data centers, Private clouds, and campus networks, because in these scenarios, network devices and virtual opportunities multiply, so that the network topology is overwhelmed. Some people think that OpenFlow is a bit like VMware in virtualization. It can control the
design and production cycle, it is a product that integrates integrated circuit technology closely with the whole machine or system technology of specific users,
Compared with general integrated circuits, it has the advantages of smaller size, lighter weight, lower power consumption, higher reliability, higher performance, enhanced confidentiality, and lower cost.
FPGA (Field Programmable Gate Array) is one of the most integrated circuits (ASIC). Y
understood as in addition to single-chip microcomputer, DSP, FPGA and the like to call out the class of IC, the rest is ASIC. The original microcontroller is not an ASIC. For example, many manufacturers provide the design of the ASIC Gate array, but the above lead layer design can be defined according to customer design to achieve custom logic, this kind of

photoThis series of H. IP cores have been listed in the form of RTL source code for ASIC applications, or in the form of RTL source code and Web tables for programmable device FPGAs. In addition, Jointwave has formed several high-performance demonstration and reference design platforms. This reference design connects two FPGA boards or UDP interfaces to the PC via the UDP interface, which obtains video uncompressed data from the HD player. The FPGA i
I am a "low-key" person, always do not like to express, to the opposite sex, the same is true for work. Under the encouragement of Xiang elder brother, I decided to write down some experiences and thoughts of my work and share them with fellow colleagues.a general-purpose parallel design method in ASIC design:1) The concept of the water network proposedthe control in IC design has both serial and parallel thinking. The state machine method responds to
Core switches are worth learning. Here we mainly introduce the NP + ASIC core switch design technology. Currently, several common feasible technologies that constitute the core switch design system are as follows:
1. General CPU
The advantage of general-purpose CPU is that the function is easy to expand and can theoretically implement any network function, but the disadvantage is that the performance is low. Therefore, in the core switch design model,
Data synchronization with same-frequency/different Phase Clock domainsWhen data was transferred from one clock domain to another clock domain, and the the and the clock domains be at the same clock-fr Equency, and is different clock phase for the both clock domain has different clock tree as show below.From the figure, there is several important points to be highlighted.
The both clock domain's clock tree should be the same source;
Same PLL ' s output;
Different PLL, but sam
