Wand problem

[Altera_Forum]

I am new to Quartus II trying to use "wand" in Verilog as I have been always using on other FPGA development tools... 

I get "signal has multiple drivers".... This for MAX10 is there limitations or options?? Neither run into this problem in 20 years. Thanks Guy

okay... looks like you are another expert user from X background....that structural data type seems only for X only... 

 Maybe you can try to migrate most of the design from the below guide.  http://www.pldworld.com/_altera/html/_sw/qts-x2a_migration.html https://www.altera.com/en_us/pdfs/literature/an/an307.pdf

What devices have you been using? Wired and is not possible inside an FPGA, and hasnt been for a very long time (if ever). 

If it worked in other tools, it would have been creating logic to emulate wired and.  Basically - dont use it.

hi Tricky, i read some doc the wind structural data type is seems belongs to product X..... hehe

You can say Xilinx here. 

There are differences between the two tools, but the technology is roughly the same. So Xilinx decides to support wand and Quartus doesnt. Either way, it doesnt synthesis to wired and.  So if you want to make it work in Altera, you cannot use wand.

hi guyp87, as the our forum master mentioned, there is a give and take occasion when we here to choose either Xilink or Altera.
