Hi,Can any one tell me that what are all the customer requirments in making a chip?

Re: customer requirments

I think It is depend on the customer that you are targeting -

But the general answer for your question will be - Logical and functional requirement of your customer and cost of chip that the customer is intended to get...

Good Luck
Re: customer requirments

thx for your reply,Can you briefly explain Logical and functional requirments?

Re: customer requirments

Ok let consider very simple example that your customer want to have Display module with 4 seven segment displays then your chip will require to have at least 7 output Data display pins and 4 output control pins.... So this is one of the type of functional requirement .... now logic requirement your need to have a logic facility of making these 7 Data Pins 1 or zero based on number send ....similarly you need to have logic faciltiy to make 4 control pins 1 and 0 also you need have timer to time the switching the pins...

This is bare minimum requirement ....

Good Luck
Re: customer requirments

Hi tyuga454,

That is the very basic question. Costumer's requirement depends on their projects, but in general following things are generally considered:
* Cost of chip.
* Area required to fabricate the chip.
* power requirement.
* Speed.
* Operating Temparature.

Generally, cheap chip, with minimum area, low power requirement, max. speed and wide operating temperature are always desirable. However you cannot achieve all this specifications at a time. there always exist a Trade-off, for ex. if u want high speed,u cannot get low power. If u want low power, u have to compromise with the speed. There are several other parameters where trade-off exists.

So, in a nutshell it always depend on the specific requirement of the chip, depending on which the design is finalized. However designers always try to optimize their design considering all the factors.

I hope so that this is not some test for tetrachromate. :smile:

Fist, question is not precise and require wide answer, but we can give short. We dont know which customer and what are their needs. Often this is based on needs/price.

But can be :

1. Function and purpose of that IC and IC capabilities to support some standards.
2. Easy implementation/programming/compatibility.
3. Temp range/case protection/case variant/dimesions.
4. Speed/reliability/power consuption
5. Price

Best example of all of this is exibitionism in mobile phone area.
