Run all three stages
Start simulate, synthesize and build with one button, and follow the build phase by phase.
Run all three stages#
On Overview, Run all three stages starts Simulate, then Synthesize, then Build the chip. Each stage starts only after the one before it has passed.
- A line under the heading shows which stage is running.
- Stop after the current stage lets the stage that is running finish and does not start the later ones. If the next stage has already started when you press it, that stage is the one that finishes; the message under the heading names it.
- If a stage fails, the later stages are not started, and the card for the failed stage shows why.
Buttons after a stage has passed#
Once a stage has passed, its button reads Simulate again, Synthesize again or Build the chip again, and the button that opens the result becomes the main one.
Following a build#
While Build the chip runs, its card shows a bar in seven parts. Each part turns green when that phase finishes.
| Phase | What is happening |
|---|---|
| Prepare | Checking the code and turning it into gates |
| Floorplan | Setting the chip's size and power grid |
| Placement | Putting every logic cell in position |
| Clock tree | Delivering the clock to every flip-flop |
| Routing | Drawing the wires between cells |
| Timing | Checking that signals arrive in time |
| Sign-off | Checking the layout against the manufacturing rules |
The bar follows the build's own log. It never guesses: if the build is slow in one phase, the bar waits there.
