Leonardo or Galileo users may encounter the following errors during NGDBUILD (Flow Engine Optimize):
ERROR:basnb:79 - Pin mismatch between block "miss1188", TYPE="preyes", and file "/home/pbm/preyes.ngo" at pin "q_out(7:0)(0)". Please make sure that all pins on the instantiated component match pins in the lower-level design block. (Pin-name matching is case-insensitive.)
ERROR:basnu:93 - logical block "pm1188" of type "preyes" is unexpanded.
This error is caused by bus-notation mismatches between Exemplar's EDIF and other vendors' netlists (e.g., LogiBLOX). Exemplar, by default, uses bus arraying in its EDIF netlists, which NGDBUILD does not understand.
FOR LEONARDO USERS:
When writing the EDIF netlist, bus arraying must be disabled. To effect this change, do ONE of the following:
1. In the Write dialog box (Menu: IO -> Write, or Flow Guide: Write), click the Advanced button. In the Set Write Variables dialog box, UNSELECT the following option:
Allow writing arrays (busses) in EDIF output
Click Set, then proceed with the EDIF Write as normal.
2. If you are processing the design from the Leonardo command line or from a script file, add the following set command before your write command:
set edif_write_arrays FALSE
FOR GALILEO USERS:
Buses must be expanded when writing the EDIF netlist. There is no checkbox that sets or unsets this option in the Galileo GUI. The change can be made via a 'Special Option' in the GUI, or in a command file:
Using the Galileo GUI: ---------------------
1. In the Galileo GUI click on the Synthesis Options icon. In the Synthesis Options windows add the following to the 'Special Options' field:
2. Synthesize the design in Galileo as normal.
Using a Command File: --------------------
1. If you do not already have a command file, create one in a text editor. Add the following line to your command file:
2. Set this newly created file as your command file. From the main Galileo window, Choose Options -> Control Files from the menu bar, or in the RUNTIME OPTIONS panel, click Control Files. In the Logic Explorer Control Files dialog box, set the Command Files field to the filename of the command file from Step 1, then click OK.
