This is not a real interface.
It is just a demo tool. The Softmark "interface" is locked to the Softmark application. With this, you can only enter manually one GPIB request at a time. Forget any real GPIB control from your program or using a virtual COM channel going to GPIB like the others...

Replying to melc, my opinion is that I still search for what reason Mentor would deserve that "5 stars" in EDA support. It would be more like 5 black holes. There is a mountain of of bugs that are very easy to fix and nonetheless get trashed as "will not fix". There...
Yes, lock is a super-fix that you would normally use for cells/parts that will
never move again. A good example is the cells for which the position is set
by mechanical constraints. E.g. the connectors, screws, leds...
You lock the above parts/cells first then finish placing the remaining parts...
mentor design capture tutorial
Altough there has been pdf's that looked like a user guide to the Mentor
ExpeditionPCB tools suite, my worst grief against this suite is the lack
of a true manual covering all topics in a logical and printable way.
In fact, the only choices left to the customer...
My 2 cents to this topic :
- Microstrip has lower loss due to the fact that air is less lossy than board dielectric -> better for high frequencies like PCIe
- Stripline needs thinner traces to achieve same impedance than microstrip -> better density
- Copper thickness on internal layers is...

There is a scale symbol function available in the library manager.
Simply search for "symbol scale" in help
I typed a much longer reply but a stupid :twisted: timeout on the login of the reply page trashed my answer.
I suppose no edaboard admin ever...
how to create a motherboard
Harbinger,
When you thing you may apply "hobby" methods like floating wires in a design
using signal edges in the GHz range, immediately forget about it. Even bringing
power to the CPU will be impossible. Decoupling lengths to the lowest valued
caps are in the range...
USB cat5 repeater
I have to install a logitech globe/sphere webcam at about 10m from
inside a building. The webcam will be enclosed in a glass dome and
exposed to very very harsh environmental conditions, i.e. cold, wind and
lightning.
I know that there are commercial USB extenders that go...
You are right :D For other interested people, I found it at this address:
**broken link removed**
It is called a tetrahub as you said, ref F5U231.
Anyone else, another models known, specially in europe ?
Thx
Does anybody have an idea about how USB2.0 hubs manage
multiple USB1.1@12Mbps devices.
I.E., a four channel USB2 hub is connected to four USB1.1 devices working
at 12Mbps. Is the hub able to convert the 4 streams to USB2 and give access
to the simultaneous aggregated 48Mbps bandwith? Or is it...
Re: matlab to vhdl
You have also Xilinx's System Generator. Test algorithms in Matlab then
implement them in Xilinx FPGAs. I don't know if intermediate files are HDL or EDIF.
mentor graphics wg2004
Hi, I don't know much about EN2004 but I am using ISD/WG2004.
So :
- EN means ENterprise while WG means WorkGroup level tools
- Expedition PCB is the PCB layout tool of the WG2004 PCB suite
- ISD2004 is the Integrated Systems Distribution, a disk collection containing...
Re: EXPEDITION PCB help
I mentioned this problem earlier on this forum and also complained to Mentor.
It is quite clear that no real detailed manual exists for the WG suite and its tools
(DC, DesignView, ExpeditionPCB, Library Manager mostly).
In fact, the so called manual is more something...
