Design vs. Debug time

--- Quote Start ---

I am wondering what forum users are spending time on.

What percentage of time is spend on design vs. debug?

It depends on what you consider 'design' time and 'debug' time.

If you design the HDL component of your system using the Modelsim simulator, and construct models for all the devices you interface to, then that takes most of the 'design' time.

If the design works in Modelsim, and you've got your hardware constraints correct, and the hardware does not have any issues, then 'debug' can be quite quick.

If you are bringing up new hardware, then the 'debug' time can be quite long depending on how many interfaces need to be tested, and whether your assembly house has done a good job of testing parts.

But before you even start a custom board design, you should really start with a known-good evaluation board. So then you have to create some designs for that ... but the board could need some debugging too ...

Did you want to be more specific?

it really depends. a well designed and tested system, included well designed tests, will minimise debug time. But a badly designed system will increase debug time.

But there theres that little bug that refuses to be found!
