The Leadership

I always admire great leaders of History & some leaders of today's generations irrespective of which side they are right or left(Wrong) but i really look up to them
and try to learn from their stories & interviews.

i work in a software firm & my previous organisation we working on one of the good project and client was happy with our work but as a professional we were not feeling satisfied because during project we were not be able to learn new technology.so,we went to our manager expressed our concern & conversation heated up manager said "SOME HOW I HAVE TO RUN THE SHOW".personally i didn't like this attitude i understand there are constraint for manager but he should have conveyed the same massage different way.Here i found the difference between Manager & Leader.




Lord Ganesha is great symbolic leader ship icon in India & Look at the picture above Leader should have quality like that.Few points i would like to add here...

Big Head: Long range thinking power

Small but sharp Eyes: Leader should see pain point of every followers

Large Ears: He should listen to even a small followers

Big stomach: Able To digest Everything & any kind of conditions remain strong in front of followers.

Half Tooth & Full Tooth :Half tooth symbolise that Leader Might not know the minor detail of subject/problem but second full tooth symbolises willingness to resolve a problem.Leader may not have in depth knowledge of subject but willingness to resolve issue is necessary.


To be a great leader requires to have above mention quality other wise they end up being manager & in future i would like to be known as good leader rather then a Manager.

Recently i came across a nice conversation between Mr. Narayana Murthy A great leader of my generation ,i always look up to him for inspiration & spiritual guru Mr Deepak chopra.It was about Leader ship & success.

Please check this conversion on Leadership Mantra which truly an inspirational & highly motivating.

Generic Interface Inspector in System Verilog

Today complexity of chip is increased so the complexity of verification process because of time to market factor & quality of deliverable. In Entire Design Cycle from specs to silicon verification is process which takes maximum time in cycle. if we can get rid of some of verification effort then we should beat TTM factor with quality deliverable.

So the Re usability is a need of an hour to achieve this goal.
How we can resolve this issue and what exactly we re-use to achieve our goal ?


In Design cycle there are two different type of functional verification we target.Module level verification & Chip Level Verification. Almost all the peripherals inside SOC we use to verify first at module level and then we test the same peripheral inside the system. We target similar behaviour of the peripherals in both type of verification. But we use to verify same peripherals separately in both the level with same scenario & checks. we build different components to verify the same thing in different environment which takes lot of time to code components and to verify it.

During Verification process of standard protocols we use to verify design against all the Rules at pin level & block levels.Most of the protocols have Host & Device (Master or slave) blocks which communicate through the common bus for data transfer.

if you compare checker rule list of all standard protocols you will find that most of the checks are common at pin level and at block level.we need some mechanism which allow us to to re-use this common set of checks across different standard protocols and different kind of verification environment(Module & SOC).


if somehow we can reduce this gap by using same components in both type of verification & different protocols then it will save most of time of coding and we can beat TTM with Quality deliverable.

This protocol interface inspector provide library of common checks at block level,pin level & timing level which user can access from library & implement their own set of check rules by directly using or enhancing the task or function from libraries.

This Generic Protocol Interface Inspector probe to this common bus to access the data on the interface and validate against all the rules should be followed by standard protocol from Both Host & Device level by using common library developed implement protocol related checks. it will inspect transaction from host & validate it and expect some transaction from Device and validate transaction from device.

This Protocol Interface inspector will also verify the timing related rules on bus using assertion & also provide hook for enhancement to verify more rules by user.

This Protocol Interface Inspector will also verify Pin level activity on the Bus for example during certain mode of operation behaviour of pins changes & this protocol inspector validates pin level activity against all protocols pin related rules.

These Protocol Interface inspectors have Host Level & Device Level Blocks to verify all the Rules of given transaction from Host & Device.

This Protocol Interface inspector will do coverage analysis on the Bus and generate report of functionality coverage of interface. it also give report of all scenario & Errors.

This Protocol Interface will check all the rules, pin level assertions & coverage data to early verification closer.


We can use this Protocol Interface to Verify most of the standard protocols by using common library & also to verify any standards protocols Host Module, Device module at module level & Inside SOC as independent component. We need to connect all interface ports to this protocol inspector and all rules related to protocol will be verified.


so, this Generic Protocol Inspector reusable which can save lot of coding time of verification process.

Pa Pa Pagleeeeee..

Today i am daring to start writing blog bcoz i think i am not a good writer but i thought let me share my thought with rest of the world.so, let start my pa pa paglee(a child who just try to walk) in blog world. while coming back from office lot of thoughts were running into my mind.due to slowdown & current scenario of job market.not a single positive news in last few days & its been verylong since i heard any good news.i don't remember when last i heard any good news but its life & wehave to move on with keeping hope alive.now a days i am reading LK adavani's autobiography(My County My Life) & i came accross nice thought "TOUGH TIMES DON’T LAST; TOUGH MEN DO".we all know this situation will not remain for a long & one day some good news will come. When i reached to my home & my little princess vaishvi (she is just one year old)looked at me and gave 1000 watt smile & threw all toys from her hand and started running (On her knee) towards me.i took her in my hand and forgot all tension, worries & tiredness within one second. After one hour i was playing with her & during that i found that she is now be able to stand on her own feet without any support then she slowly started walking around 3-4 step(In gujarati we use to say PA PA PAGLEE...) & then she fall down on my hand.i was amaze to see that & coudnt explain my feelin. its always amazing to see when your kid is standing on her feet & you want to share your joy with rest of the world(Thats why i started wrting blog..ha ha ha).so,i thought let me share this first with my parents and i called up to bhuj to give this news.my parents were delighted to know that vaishvi has actully started walking & my papa told me its not only good but a great news. At 7 pm i was worried about good news & at 10 pm on same day i was giving great news to my parents.
