Program Block Vs Module In System Verilog

System on a chip Wikipedia. The Raspberry Pi uses a system on a chip as an almost fully contained micro computer. This So. C does not contain any kind of data storage, which is common for microprocessor So. C. A system on a chip or system on chip So. C or SOC is an integrated circuit also known as an IC or chip that integrates all components of a computer or other electronic systems. It may contain digital, analog, mixed signal, and often radio frequency functionsall on a single substrate. So. Cs are very common in the mobile computing market because of their low power consumption. A typical application is in the area of embedded systems. So. C integrates a microcontroller or microprocessor with advanced peripherals like graphics processing unit GPU, Wi Fi module, or coprocessor.

Program Block Vs Module In System Verilog' title='Program Block Vs Module In System Verilog' />If the definition of a microcontroller is a system that integrates a microprocessor with peripheral circuits and memory, the So. C is to a microcontroller what a microcontroller is to processors, remembering that the So. C does not necessarily contain built in memory. In general, there are three distinguishable types of So. Cs. So. Cs built around a microcontroller, So. Cs built around a microprocessor this type can be found in mobile phones, and specialized So. Dataflow modeling in Verilog allows a digital system to be designed in terms of its function. Dataflow modeling utilizes Boolean equations, and uses a number of. Cs designed for specific applications that do not fit into the above two categories. A separate category may be Programmable So. C PSo. C, where some of the internal elements are not predefined and can be programmable in a manner analogous to the FPGA or CPLD. When it is not feasible to construct a So. C for a particular application, an alternative is a system in package Si. P comprising a number of chips in a single package. When produced in large volumes, So. C is more cost effective than Si.

Another option, as seen for example in higher end cell phones, is package on package stacking during board assembly. The So. C includes processors and numerous digital peripherals, and comes in a ball grid package with lower and upper connections. The lower balls connect to the board and various peripherals, with the upper balls in a ring holding the memory buses used to access NAND flash and DDR2 RAM. Memory packages could come from multiple vendors. AMD Am. 28. 6ZXLX, So. C based on 8. 02. Structureedit. Microcontroller based system on a chip. A typical So. C consists of a microcontroller, microprocessor or digital signal processor DSP core multiprocessor So. Cs MPSo. C having more than one processor corememory blocks including a selection of ROM, RAM, EEPROM and flash memorytiming sources including oscillators and phase locked loopsperipherals including counter timers, real time timers and power on reset generatorsexternal interfaces, including industry standards such as USB, Fire. Wire, Ethernet, USART, SPIanalog interfaces including ADCs and DACsvoltage regulators and power management circuits. A bus either proprietary or industry standard such as the AMBA bus from ARM Holdings connects these blocks. DMA controllers route data directly between external interfaces and memory, bypassing the processor core and thereby increasing the data throughput of the So. C. Design flowedit. System on a chip design flow. A So. C consists of both the hardware, described above, and the software controlling the microcontroller, microprocessor or DSP cores, peripherals and interfaces. The design flow for a So. C aims to develop this hardware and software in parallel. Most So. Cs are developed from pre qualified hardware blocks for the hardware elements described above, together with the software drivers that control their operation. Of particular importance are the protocol stacks that drive industry standard interfaces like USB. The hardware blocks are put together using CAD tools the software modules are integrated using a software development environment. Once the architecture of the So. C has been defined, any new hardware elements are written in an abstract language termed RTL which defines the circuit behaviour. These elements are connected together in the same RTL language to create the full So. C design. Chips are verified for logical correctness before being sent to foundry. This process is called functional verification and it accounts for a significant portion of the time and energy expended in the chip design life cycle although the often quoted figure of 7. With the growing complexity of chips, hardware verification languages like System. Verilog, System. C, e, and Open. Vera are being used. Bugs found in the verification stage are reported to the designer. Malaysia Patch Fifa 2005 there. Traditionally, engineers have employed simulation acceleration, emulation andor an FPGA prototype to verify and debug both hardware and software for So. C designs prior to tapeout. With high capacity and fast compilation time, acceleration and emulation are powerful technologies that provide wide visibility into systems. Both technologies, however, operate slowly, on the order of MHz, which may be significantly slower up to 1. So. Cs operating frequency. Acceleration and emulation boxes are also very large and expensive at over US1 million. FPGA prototypes, in contrast, use FPGAs directly to enable engineers to validate and test at, or close to, a systems full operating frequency with real world stimuli. Tools such as Certus4 are used to insert probes in the FPGA RTL that make signals available for observation. This is used to debug hardware, firmware and software interactions across multiple FPGAs with capabilities similar to a logic analyzer. In parallel, the hardware elements are grouped and passed through a process of logic synthesis, during which performance constraints, such as operational frequency and expected signal delays, are applied. This generates a logical netlist which is a file describing the circuit as a collection of connected silicon gate elements from a library provided by the silicon manufacturer. This netlist is used as the basis for the physical design place and route flow to convert the designers intent into the polygonal design of the So. C. Throughout this conversion process, the design is analysed with static timing modelling, simulation and other tools to ensure that it meets the specified operational parameters such as frequency, power consumption and dissipation, functional integrity vs. RTL and electrical integrity. When all known bugs have been rectified and these have been re verified and all physical design checks are done, the physical design files describing each layer of the chip are sent to the foundrys mask shop where a full set of glass lithographic masks will be etched. Kill Bill 2 Tr. These are sent to the wafer fabrication plant to create the So. C dice before packaging and testing. FabricationeditSo. Cs can be fabricated by several technologies, including So. C designs usually consume less power and have a lower cost and higher reliability than the multi chip systems that they replace. And with fewer packages in the system, assembly costs are reduced as well. However, like most VLSI designs, the total cost is higher for one large chip than for the same functionality distributed over several smaller chips, because of lower yields and higher non recurring engineering costs. BenchmarkseditSo. C research and development often compares many options. Benchmarks, such as COSMIC,5 are developed to help such evaluations. See alsoeditReferenceseditPete Bennett, EE Times.
