XADC is actually already used in the SDRAM controller?.because it's uber fast
DDR3 it's used to measure temperature and dynamically adjust signal timing.
Recursively search for mig_7series_v1_8_tempmon.v under usrp3/top/X300/coregen

Ah, thanks for the information.
What's interesting is that I'm able to build and implement with an XADC
module instantiated without Xilinx firing off any warnings to me. One would
think that Xilinx would warn you about that :-)

Hi Robert,
You are building the HGS image and not the HG image, right? The "S"
signifies an SRAM TX buffer and does not instantiate any of the DRAM IP.
That is probably why you are not seeing any warnings. If you build X300_HG
(or X310_HG) I'm sure the tools will complain.

Hi,
Just got the b200 streaming nicely on 64-bit Windows 8.1, nicely impressed.
Questions will follow.

Subject: [USRP-users] b200 Overflows
Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
Hi,
Windows 64-bit: I'm streaming nicely, none of my threads indicate CPU
problems (plenty of headroom). At 8MB/s and higher I'm getting fastpath
Overrun messages every second or so even though I'm pulling data from the
b200 as fast as it's available, I am not CPU limited in any way. Using Intel
USB 3.
FWIW I don't see any way to tune the uhd::rx_streamer - bigger / more
buffers, also I don't see any way to flush either.
Interestingly if I get my CUDA card working harder (more work on the bus)
the Overrun messages appear more frequently. I7 4770k, good motherboard
(can't remember what).
Any suggestions?

Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
Hi,
Windows 64-bit: What's the logic for searching for the b200 and other Ettus
FPGA / firmware images? I've looked though the code but am confused. Is
there any way I can specify the folder where the images are found or is the
logic PATH / local folder. ?

The USB transport parameters can be tweaked:

I think if you use a complete path here:
http://files.ettus.com/manual/page_usrp_b200.html
It'll fetch the FPGA or FW images from exactly where you specify.
There's also a UHD_IMAGE_PATH environment variable that can be set to
override the default
