Design And Verification Related Modules For System On A Chip DCR、 OPB、 Bus

Owing to the continuous development of the semiconductor technology, ICdesigners can integrate some complex functions onto a single silicon chip. It is in thetrend that IC turns to IS, System on a Chip appears as the times require.System on aChip makes the technology of IP resue begin to appear, which is of great significanceto the integration of many IP, so the efficiency of on-chip bus and interface determinesthe efficiency of SoC.This paper design some reuse-able modules based in the DCR and OPB bus,including eight PWM modules, four road frequency collector modules and the threerode fibre code modules. Their design ideas as well as the design goal were analyzed.For every module, the test bench is made by using direct measurement method. Inorder to check the output of each module, the incentive of input is given.After designing the modules, when each module is connected with thecorresponding bus, the input data cannot be gathered as expected, adding asynchronous module can avoid this state. The three modules can be used in otherdesigns which contain the similar bus. We can save time of design by using thesemodules directly in other designs, which is the significance.
