ABSTRACT

0ultiprocessor system on chip is emerging as a new trend for

system on chip design but the wire and power design constraints are

forcing adoption of new design methodologies* Researchers pursued a

scalable solution to this problem i*e* 1etwor+ on !hip %1O!(*

1etwor+ on chip architecture better supports the integration

of SO! consists of on chip pac+et switched networ+* $hus the idea is

borrowed from large scale multiprocessors and wide area networ+

domain and en'isions on chip routers based networ+* !ores access the

networ+ by means of proper interfaces and ha'e their pac+ets

forwarded to destination through multichip routing path*

In order to implement a competiti'e 1O! architecture, the

router should be efficiently design as it is the central component of1O! architecture* In this paper we implement a parallel router which

can support fi'e requests simultaneously* $hus the speed of

communication can be increased after reducing communication

bottlenec+ by suing simplest routing mechanism, flow mechanism and

decoding logic*

the latest 'erification methodologies, 4ardware 'erification languages

and 2A tools and qualify the IP for synthesis an implementation*

567 of ASI! resins. are due to functional bugs* As the functional

'erification decides the quality of the silicon, we spend 867 of the

design cycle time only for the 'erification9simulation* In order to

a'oid the delay and meet the $$0, we use the latest 'erification

methodologies and technologies and accelerate the 'erification

process*

$his project helps one to understand the complete

functional 'erification process of comple- ASI!s an Soc.s and it gi'esopportunity to try the latest 'erification methodologies, programming
