Asked Questions
ANSWERS to all Frequently Asked Questions
1. What is the Nexus 5001™ Forum?
2. Who are the members of Nexus 5001™ Forum?
3. How can my company/organization become a member of
the Nexus 5001 Forum?
4. Is this standard applicable globally?
5. Are there any licensing or royalty fees involved?
6. How is the interface different from existing
interfaces and what makes it so innovative?
7. Is this new open standard compatible with any
available interface?
8. Why are we introducing this interface standard now?
9. Will this standard obsolete existing interfaces on
MCU's today?
10. Will customers be able to easily adopt to this
standard-interface?
11. How can my company be involved, provide inputs,
and get technical information?
12. Is it the intention of the Nexus 5001™ Forum to
make this an IEEE standard?
13. Are other companies planning to endorse/adopt the
standard?
14. How will compliance to the standard be verified?
15. What does this interface offer and what are the
key benefits for customers?
16. Which application areas will benefit the most from
this standard?
17. Will the H/W interface be 100% compatible between
different MCU's?
18. Does this mean that all Nexus 5001 compliant tools
will be the same?
20. When will the tools be made available to support
the interface?
21. When can customers expect to see silicon based
products?
22. Is this standard applicable for 32-bit MCU's only?
23. Does the interface support rapid prototyping and
real-time simulation?
24. The standard appears to be very automotive biased
and specifically focused towards powertrain. Do you have other
applications outside of the automotive arena targeted for the Nexus
5001 interface and, if so, when will this happen?
25. How fast a CPU frequency does the standard
support? What is the maximum operating frequency? What is the interface
frequency?
26. Does the Nexus 5001™ Forum Standard take into
consideration calibration capacity?
27. Can we use a Nexus 5001™ interface for rapid
prototyping?
28. Is the scope of the Nexus 5001™ Forum Standard
limited to specifying just the auxiliary pins?
29. Is there a requirement within the Nexus 5001™
Forum Standard for special additional tools?
30. Regarding data monitoring, how many data values
can the user monitor?
31. Does the Nexus 5001™ Forum only approve HP and
ETAS as tool vendors? Will other tool vendors be allowed to implement a
nexus specification on their own tool chain?
32. Will the Forum limit any patent or API of the
Nexus 5001™ interface throughout the other semiconductor manufacturers?
33. How fast will the trace-sampling rate be for use
with an RTOS?
34. Is security protection for on-chip flash memory
specified in the Nexus 5001™ Forum Standard?
35. Cables and/or interconnects within an engine test
setup can ofter be susceptible to noise and EMC. Does the Nexus 5001™
Forum Standard address this common problem?
36. Are there any software standards from Nexus (API)
applied to the interface along side the protocol layer?
37. Is there commitment from semiconductor vendors to
support non-automotive applications?
38. Does the Nexus 5001™ Forum realize some security
levels as found in the CAN/car calibration (CCP2 standard for
measurements)?
39. Is it possible that there will be too many
external parameters to handle as they are serially moved back and forth
via the auxiliary pins to external virtual memory?
40. Does the Nexus 5001™ Forum define a minimum Nexus
auxiliary port of 16 pins?
41. Does the Nexus 5001™ Forum intend to provide the
VHDL code for the Nexus interface description?
