Abstract

Disclosed is a tool for automating the timing analysis of devices to be connected to a computer bus, such as the Micro Channel*, based on the concept of using a model in simulation to generate a table listing the timing characteristics of the bus cycle.

MICRO CHANNEL Verification Laboratory Tool

      Disclosed is a tool for automating the timing analysis of
devices to be connected to a computer bus, such as the Micro
Channel*, based on the concept of using a model in simulation to
generate a table listing the timing characteristics of the bus cycle.

The Micro Channel Verification Laboratory Tool (MCVLT) further
analyzes this table to list bus cycle violations and instances when
timings are close to the limitations of the bus architecture without
causing a violation.  MCVLT also provides a means for translating the
bus cycle information captured by a logic analyzer into a form that a
simulator can use for analysis.

      As shown in Fig. 1, to use MCVLT, an adapter circuit 1 to be
tested is placed in a test station 2, connected to a logic analyzer
4, such as a DAS 9200 or a Hewlett Packard 16500.

      The features of MCVLT are contained within two software
programs, the first of which is the timing analysis tool software 6,
which monitors Micro Channel cycles on the bus, flagging all timing
violations.   This software provides a timing characteristics table,
an example of which is shown in TABLE 1, listing by name every
relevant Micro Channel timing parameter of the cycles monitored,
along with the time recorded from the bus and a simulation time
stamp.  This software can be run on an RS/6000* or mainframe computer
8, residing in the AUSSIM simulation environment.
 In this configuration, computer 8 is conn...
