• 723 - Lattice Diamond: PAR: What's the best way to place and route a congested design?

  Lattice Diamond: PAR: Here are some guidelines when handling a congested design. Always use the latest software for synthesis, map, and place and route. Both synthesis vendors and FPGA companies are constantly fine-tuning the tools to make them more ...

• 1712 - Diamond: How can user get estimated timing of my design before running place and route?

  In both ispLEVER and Lattice Diamond tools, user can generate the timing using the static timing analysis tool after map, and before place and route. The static timing analyzer (TRCE) will generate timing using estimated models, as well as the fanout ...

  Lattice ispLEVER: Place and Route: In congested designs a conflict may occur resulting in an unroutable condition in PAR. This may be due to user constraints or unfavorable placement of logic by the software. Depending on the size and complexity of a ...

• 1993 - Diamond: Why does the place and route tool not fix hold violation for the design despite Auto Hold-Time Correction being set to "On"?<br>

  The tool disables Hold-Time Correction due to the following reasons: 1. If there is a setup timing error, auto hold-time correction will not be done. If user wants the correction to be done anyway, add the following option to “Command Line Options” ...
