Qsys port order in the symbol file (.bsf) ... random? How to fix? (v.12.1SP1)

Altera_Forum · ‎04-29-2013

Hi, I had to transform an SOPC bilder System created in Quartus 9.1 to a Qsys System in Quartus 12.1SP1 ...

But now I'm running into a very frustrating issue with qsys ... I hope I'm missing some simple thing.

The problem is I have a sysq-system and I use schematics as the top level so I create a symbol file of course from qsys and instantiate it at the top level ...

Now, when I do some modification in the Qsys and regenerate and subsequently update the symbol then all pins get randomly changed to differnt locations in the symbol ...

How can I fix this? It is most annoying to shuffle all pins again to the right pins!!!

SOPC never did this before!!!

I need to fix this problem because I suppose that I'll have to insert more other PIO and ports and I can't change the schematics connection everytime!!!

Help me!

Thanks!

You cant stop this. THe only workaround would be to do the top level in HDL and use named association.

Hi,

I have the same Problem with .bsf generation in QSYS v.12.1sp1 ...

I had a .bsf built with QSYS v.11.1sp2, which looked quit usable

After compilation with 12.1sp1 everything was scrambled :mad:

The old 11.1-bsf begins with

...
(header "symbol" (version "1.2"))
(symbol
 (rect 64 64 384 1512)
 (text "fpga_backup" (rect 148 -1 234 15)(font "Arial" (font_size 10)))
 (text "inst" (rect 8 1432 25 1444)(font "Arial" ))
 (port
  (pt 0 72)
  (input)
  (text "clk_clk" (rect 0 0 37 14)(font "Arial" (font_size 8)))
  (text "clk_clk" (rect 4 61 41 75)(font "Arial" (font_size 8)))
  (line (pt 0 72)(pt 128 72))
 )
 (port
...

The new one (v12.1) begins with

...
(header "symbol" (version "1.1"))
(symbol
 (rect 0 0 512 1448)
 (text "fpga" (rect 244 -1 261 11)(font "Arial" (font_size 10)))
 (text "inst" (rect 8 1432 20 1444)(font "Arial" ))
 (port
  (pt 0 72)
  (input)
  (text "in_port_to_the_data_link_irq" (rect 0 0 113 12)(font "Arial" (font_size 8)))
  (text "in_port_to_the_data_link_irq" (rect 4 61 172 72)(font "Arial" (font_size 8)))
  (line (pt 0 72)(pt 224 72)(line_width 1))
 )
...

Is it possible that QSYSv12.1 uses an older bsf-generator ???

The bsf-syntax seems to be quite simple, so it shouldn't be a big issue to build a TCL-script,

which makes a .bsf looking like the good old SOPC-symbols :-)

I haven't found a documentation of the .bsf syntax so far. So I tried to comment my

automatically generated one....

...
(header "symbol" (version "1.2"))
(symbol
  (rect x1 y1 x2 y2)                         --> the rectangle for the symbol
  (text "<title>" (rect ....)(font "..."))   --> Title of the QSYS-System
  (port
    (pt x y)                                        --> coordiates of the connection point
    (input)
    (text "...." (rect 0 0 x y)(font "..."))     --> ?? ist it the signal name of the port
    (text "...." (rect x1 y1 x2 y2)(font "..."))    --> Text which appears as node name
    (line (pt x1 y1)(pt x2 y2)(line_width 3)        --> line to the port (Bus has line_width 3)
  )
  (port
....
)

maybe I've to play around a bit...

... but maybe somebody already has done it :)

Regards,

Not quite what you're looking for, but the SOPC Builder "version 1.1" format is produced by the Perl script in sopc_builder/bin/mk_bsf.pm Yes it looks pretty simple.

An alternate way to work around this problem is to use Quartus to produce your own .bsf file from a modified copy of your Qsys top-level .v or .vhdl file.

In other words, create a copy of the top-level HDL file, modify the ordering of the ports, and then use Quartus File->Create/Update->Create Symbol for Current File... to have Quartus parse and generate a new .bsf from your modified file.

You would only have to repeat this process each time you change the ports included in the top level Qsys.
