# Tapeout
Top level integration - connecting up all the blocks.
You need a [floorplan](floorplan.md).
## Tape-out Check-list
Key separate of I/C from discrete/PCB - no way to change when manufactured!
No extra wire, buffer, need to completely respin the chip.
Chip must be correct first time!
Such an emphasis on simulation - be sure it works.
### Procedure
- Design meets specifications?
- Circuit is LVS clean?
- DRC clean?
- Corner simulations? Easy to be lazy but it would likely not work since parameters are not typical!
- Monte Carlo sims of sensitive circuits?
- Functional sims?
- ESD in place?
- I/O - input cells for input and output cells for outputs?
- Sufficient test access? Can't observe anything on the chip if you haven't thought of it in advance (multiplexer so you can route different signals).
- Proper layout - matching, power, clk, analogue and digital separate, no coupliong to sensitive nets
- Pad location compatible with PCB and packaging.
Make list comprehensive but concise.
Put in the effort and do the work implied by ticking the box
