Figure 194 Download Commands in the Binary Vector File
Observe the following points in the figure:
• The excerpt has been converted with the UNIX command vis in
order to make the binary data of the VECD command readable.
• The SQPG command downloads a GENV sequencer instruction
which says “Send three vectors to the DUT”.
• The VECD command can broadly be paraphrased as “Load the
following 28 bytes into the vector area of pin Q0 at the address 0”.
The smallest unit of the Vector Memory that can be accessed for
load operations is 28 bytes. Only the first 7 bytes of the binary data
are displayed in Figure 194 . The first 3 bytes contain the 3 wave-
form indices for pins Q0.
The vector translator also requires the pin configuration file. For
example, it needs to know the port definitions for the generation of a
multi- port setup, and the context of the pins for an NP setup.
The Overall Process
The following figure gives a comprehensive overview of the translation
process for the ASCII timing and vector file fragments of Figure 190 on
page 297 and Figure 191 on page 298. The vertical layout of the figure
roughly corresponds to the temporal order.
