scripts are only used by vManager. Use the

get it running (i.e. it may not find your tools

sample tests, and an example scoreboard.
There isn't a lot of
documentation (none, really), but I'll try to give an
There are 3 main
sequences: the BFM sequence, which controls the cycle by cycle (clock by clock)
activity on the SPI3 bus. The subtype LAYERED_PAYLOAD of this sequence is
designed to draw data from the upper layer, which is the 2nd sequence, the PORT
In it's default form
the PORT sequence generates random SPI3 "packets" or "frames." It can also be
connected to a higher layer sequence (i.e ATM, HDLC, Etherenet, whatever you
The 3rd sequence is the
arbiter sequence. This is the sequence that determines the next SPI3 "Port" on
which to drive data. It is implemented as a simple round robin "Arbiter" at
this point, but could be extended to do whatever the user
The AGENT has 4
subtypes: RX PHY, TX PHY, RX LINK, TX LINK which correspond to the 4 different
"views" of the SPI3 bus. If you know SPI3 at all, this will be

This is also a protocol

There is some very low

There are some sample
BFM sequences in the shr_bfm_sequence_lib.e file that give good examples on how
to create bus level errors and corner cases.
As I said above, the
documentation is pretty well non-existant.

I consider the eVC a GREAT starting piont, and can be used with less than 1/2 a day
effort to do very thorough sanity checking on a SPI3 block. Other Cadence customers have used it,
almost unchanged in the form I'm postin, to do VERY thorough, VERY

Ugh. That's no good. I'll try re-tarring it and I'll repost again later today.
Sorry for the delay in reposting. Here is another tar file. Hopefully this one works better.-Matt
