12.2 Project Navigator - Generating an IP core from "New Source" does not produce symbol (SYM) file
描述
InISE Design Suite 12.1 when an IP coreis generated using the "New Source" feature within the Project Navigator GUI, the symbol (SYM) file is not being created by default for schematic design.
解决方案
Any time an IP core is generated through the Project Navigator New Source process, a symbol file (.sym) should be generated if the IP core supports it.
If the ".sym" file does not exist, Schematic Editor picks up and uses the ".asy" file there is an .asy file for the core. The ".asy" file is still valid, but does not allow the symbol to be pushed into.
To get a valid symbol file, do one of the following.
From withinCORE Generator, modify the project options to choose "Design Flow" -> Schematic. Then generate the Core as normal and add it to the Schematic Design in Project Navigator
Create the Core from the "New Source" feature in Project Navigator. Then select the "Manage Cores" option in the processes window and modify theCORE Generatoroptions to use "Design Flow" -> Schematic, then "Regenerate the Core under current project options". This ultimately requires generating the core twice.
Temporarily add the HDL wrapper to the project instead of the .xco file then run Design Utilities / Create Schematic Symbol file. After the .sym file is created, remove the HDL wrapper from the project and add the .xco.
If an .asy file exists, the .sym file can be created by running asy2sym to generate the .sym file:
