|
|
Releasing a chip to production is not the end of the job. You must
|
|
still continue to maintain the design. You cannot archive a chip data
|
|
base into offline storage and simply put it on the shelf. Do you really
|
|
think that you can pull it down 20 years later and recreate the chip?
|
|
Bit Rot is real. Even if you can read the bits off the magtape that you
|
|
used to use then you will find that you can no longer get the same
|
|
version of the tools that you used to build the chip. The
|
|
original IC process will be long gone and the current ones have added
|
|
new requirements that your code doesn't meet.<br>
|
|
<br>
|
|
When you finish a chip you archive an exact copy of all the data and
|
|
freeze that forever. Your design then continues to live on. When
|
|
you get a new version of a tool you rebuild and test everything
|
|
and fix problems. As new processes come online you retarget the design
|
|
to use them. As component ip is reved you upgrade and run the test
|
|
suite.<br>
|
|
<br>
|
|
Then when your original product is winding down and someone wants a
|
|
follow up product then you have a head start.<br>

<h2>TARGET</h2>
|
|
<p>A target is a specific physical design that can implement a
|
|
component. Targets can be asic or fpga and include a Printed circuit
|
|
board(PCB) that may include other electronic components. The goal for

all components is to assign them to at least one target and prove that

<h2>PROJECT</h2>
|
|
<p>A project is a collection of components. A database must define at
|
|
least one project to create an area where components may be stored.
|
|
Other projects may be created as needed to group similar components
|
|
together and reducing clutter. If any component in a project uses a
|
|
component from a child project then that child project must also be
|
|
included in the parent project.</p>
