1323 International Journal of Advanced Research in Computer Engineering & Technology Volume 1, Issue 5, July 2012 Design and Verification Eight Port Router for Network on Chip Sana.Ranjitha,IEEE-2012,B.Vijay Bhaskar ,R.SuryaPrakash St.Theressa College of Engineering,JNTU-2012 ABSTRACT`: Multiprocessor system on chip is with less effort. Recent advancement towards this emerging as a new trend for System on chip design goal is methodologies. The methodology defines a but the wire and power design constraints are skeleton over which one can add flesh and skin to forcing adoption of new design methodologies. their requirements to achieve functional verification. Researchers pursued a scalable solution to this OVM (open verification methodology) is one such problem i.e. Network on Chip (NOC). Network on efficient methodology and best thing about it is, it is chip architecture better supports the integration of free. This ovm is built on system Verilog and used SOC consists of on chip packet switched network. effectively to achieve maintainability, reusability, Thus the idea is borrowed from large scale speed of verification etc. This project is aimed at multiprocessors and wide area network domain building a reusable test bench for verifying 8 Port and envisions on chip routers based network. Cores Router Protocol Bridge by using system Verilog and access the network by means of proper interfaces ovm and have their packets forwarded to destination In this document the use of vmm and system through multichip routing path. In order to Verilog to verify a design and to develop a reusable implement a competitive NOC architecture, the test bench is explained in step by step as defined by router should be efficiently design as it is the verification principles and methodology. The test central component of NOC architecture. Design bench contains different components and each And Verify the functionality of the “Design and component is again composed of subcomponents, Verification Eight Port Router for Network on these components and subcomponents can be reused Chip” IP core using the latest verification for the future projects as long as the interface is methodologies, Hardware Verification Languages same. and EDA tools and qualify the IP for Synthesis an implementation. Router: System on chip is a complex interconnection of various functional elements. It creates Introduction communication bottleneck in the gigabit communication due to its bus based architecture. My research is based on the paper” router Thus there was need of system that explicit design for network on chip”. Now in this paper I modularity and parallelism, network on chip possess have designed a eight port router which is the many such attractive properties and solve the advancement for the previous four port router problem of communication bottleneck. It basically network.But in the four port network we have the works on the idea of interconnection of cores using ability to connect a network of four systems which is on chip network. limited.Now I extended this network upto 8 ports The communication on network on chip is and I observed the results using verilog HDL. carried out by means of router, so for implementing better NOC , the router should be efficiently design. The challenge of the verifying a large design This router supports four parallel connections at the is growing exponentially. There is a need to define same time. It uses store and forward type of flow new methods that makes functional verification easy. control and Fsm Controller deterministic routing Several strategies in the recent years have been which improves the performance of router.

1323 International Journal of Advanced Research in Computer Engineering & Technology Volume 1, Issue 5, July 2012 switching mechanism used here is packet switching packet is driven out. The router has an active low which is generally used on network on chip. synchronous input resetn which resets the router. In packet switching the data the data .Data packet moves in to the input channel transfers in the form of packets between cooperating of one port of router by which it is forwarded to the routers and independent routing decision is taken. output channel of other port. Each input channel and The store and forward flow mechanism is best output channel has its own decoding logic which because it does not reserve channels and thus does increases the performance of the router. Buffers are not lead to idle physical channels. The arbiter is of present at all ports to store the data temporarily. rotating priority scheme so that every channel once The buffering method used here is store and get chance to transfer its data. In this router both forward. Control logic is present to make arbitration input and output buffering is used so that congestion decisions. Thus communication is established can be avoided at both sides. between input and output ports.. According to the A router is a device that forwards data destination path of data packet, control bit lines of packets across computer networks. Routers perform FSM are set. The movement of data from source to the data "traffic direction" functions on the Internet. destination is called switching mechanism The A router is a microprocessor-controlled device that is packet switching mechanism is used here, in which connected to two or more data lines from different the flit size is 8 bits .Thus the packet size varies from networks. When a data packet comes in on one of 0 bits to 8 bits. A detailed explanation of Design is the lines.the router reads the address information in as follow the packet to determine its ultimate destination. Then, using information in its routing table, it directs the packet to the next network on its journey. The router is a ” Eight Port Network Router” has a one input port from which the packet DATA out enters. It has seven output ports where the packet is packet_valid driven out. Packet contains 3 parts. They are Header, VLD out suspend_data data and frame check sequence. Packet width is 8 bits and the length of the packet can be between 1 err 8 Port Read Enable bytes to 64 bytes. Packet header contains three fields Routers DAand length.Destination address(DA) of the packet is of 8 bits. The switch drives the packet to clock respective ports based on this destination address of reset the packets. Each output port has 8-bit unique port address. If the destination address of the packet matches the port address, then switch drives the Block Diagram Of Eight Port Router packet to the output port, Length of the data is of 8 bits and from 0 to 63. Length is measured in terms of bytes. Data should be in terms of bytes and can take anything. Frame check sequence contains the security check of the packet. It is calculated over the header and data. Router is a packet based protocol. Router drives the incoming packet which comes from the input port to output ports based on the address contained in the packet The router has a one input port from which the packet enters. It has three output ports where the 43 All Rights Reserved © 2012 IJARCET

1323 International Journal of Advanced Research in Computer Engineering & Technology Volume 1, Issue 5, July 2012 Router Output Block There are 7 fifos used in the router design. Each fifo is of 8 bit width and 16 bit depth. The fifo works on system clock. It has synchronous input signal reset. 8 Port Router Output If resetn is low then full =0, empty = 1 and data_out =0 Conclusion The FIFO has doing 7 deferent operations As the functional verification decides the Write Operation quality of the silicon, we spend 60% of the design Read operation cycle time only for the verification/simulation. In Read and Write Operation order to avoid the delay and meet the TTM, we use The functionality of FIFO explain Below the latest verification methodologies and technologies and accelerate the verification process. This project helps one to understand the complete functional verification process of complex ASICs an SoC’s and it gives opportunity to try the latest verification methodologies, programming concepts like Object Oriented Programming of Hardware Four port Router FIFO Verification Languages and sophisticated EDA tools, Write operation: for the high quality verification. The FIFO write operation is done by when the data from input data_in is sampled at rising edge of In this Four Port Router project I Design and the clock when input write_enb is high and fifo is verified the functionality of Router with the latest not full.in this condition onaly FIFO Write operation Verification methodology i.e.,System Verilog and is done. observed the code coverage and functional coverage Read Operation: of Router by using coverpoints ,cross and different The FIFO Read Operation is The data is read test cases like constrained, weighted and directed from output data_out at rising edge of the clock, testcases.By using these testcases I improved the when read_enb is high and fifo is not empty. functional coverage of Router. In this I used one Read and Write operation can be done master and eight slaves to monitor the Router.Thus simultaneously. the functional coverage of Router was improved. Full – it indicates that all the locations inside fifo has The results shows that System Verilog been written. methodology can be used to make reusable test Empty – it indicates that all the locations of fifo are benches successfully. Large part of the test bench is empty. made reusable over multiple projects.even though this reusablity is limited to the interfaces.
