[hpsdr] "FPGA Floor Planning"

[Helmut]

Hi,

 

I completely agree with Stijn. 

 

Hands off these pay tools! You will give up the open source idea of HPSDR
and get independent of these FPGA optimization tools dominating the complete
firmware code. The system will get locked for people not licensed by Altera.

Just fyi,

These are the prices for Quartus per seat per year.
https://www.altera.com/buy/design-software.html#note

If we go this route, you exclude any hobbyist who wants to make his own
modifications to the code.

Just my opinion,

How is it that the free version of Quartus is sufficient when just recently
both the Angelia and Orion firmware updates required multiple, rapid
iterations and still apparently either don't work at all, don't work for
everyone, or work but have to trade-off previous functionality for new
functionality?

 

Given the current complexity of the firmware (which, by the way, only
underscores the really tremendous amount of phenomenal work that Joe and
Phil have completed over the years), timing closure has had to become more
and more difficult with the free tool. This is even more of an issue with
the new firmware protocol where there is more data, moving faster, than ever
before.

 

Another factor that is driving the need to go to a more capable development
environment is the fact that there is no lab where a firmware build can be
fully validated on a range of Hermes, Angelia or Orion boards, over
temperature, before release. This makes achieving tight timing about the
nominal range even more important such that builds that work for some and
not others are less likely.

 

Here's another suggestion: the firmware source code remains open source, of
course. And those who wish to develop on the free version of Quartus can
still do so. But it would seem that Apache Labs might want to obtain the
standard version of Quartus and someone willing and able to use it to polish
up the timing of a given build such that it will reliably work on all Apache
Labs radios under most conditions.

 

73,
