- ================================
- Welcome to Electronics Workbench
- ================================
- The Release Notes contain important information that was
- received too late to be included in the written documentation.
- They can be found in the online help. To view the release
- notes, start Electronics Workbench and choose Release Notes
- from the Help menu.
- Below is further information which was too late to be included
- in the online Help.
- ================================================================
- Parser Errors Tab
- A new tab has been added to the Analysis Graphs Window, called
- "Parser Errors". The tab appears only if errors occur during
- the parsing of a subcircuit netlist model. (Note: Parsing
- occurs after you start a simulation or analysis.)
- Most of the errors appearing in this list are only warnings.
- They simply notify the user of syntax in a netlist which is
- unsupported by Electronics Workbench.
- ================================================================
- Electronics Workbench User's Guide Corrections
- Page 5-2 - The circuit under Step 1 shows the first connection
- of the word generator connected to connector "S" and the second
- connection of the word generator connected to connector "R".
- This is reversed. The first connection of the word generator
- should be connected to connector "R" and the second to
- connector "S".
- Page 5-4 - The second point under Step 3 should state "Change
- the frequency to 1 MHz".
- Page 5-5 - The circuit under Step 1 shows the first connection
- of the word generator connected to connector "S" and the second
- connection of the word generator connected to connector "R".
- This is reversed. The first connection of the word generator
- should be connected to connector "R" and the second to
- connector "S".
- The procedure for setting the logic analyzer under Step 1 is no
- longer correct as the logic analyzer was revised after the
- printing of the User's Guide and Technical Reference.
- The new procedure for setting the Logic Analyzer is as follows:
- 1. Set the frequency of the word generator to 1 MHz.
- 2. On the logic analyzer, set the clocks per division to 1.
- 3. Click on the set button in the clock box and ensure the
- following:
- - Clock edge "negative"
- - Clock mode "internal"
- - Set internal clock rate to "1 MHz"
- - Clock qualifier "x"
- - Logic analyzer "Pre-trigger samples 100"
- "Post-trigger samples 1000"
- "Threshold voltage (V) 3.5"
- 4. Make sure the Current address on the word generator is 0000.
- 5. Click the Cycle button on the word generator.
- ================================================================
- Technical Reference Corrections
- PAGE 14-22 - The picture of the opened logic analyzer is
- incorrect. Since the manual was printed, the Time Base feature
- has been removed and replaced with a Clocks per division
- feature.
- The "Time base" setting was used to set the logic analyzer's
- display in units of seconds/division. The "Clocks per division"
- setting is used to set the traces in units of clocks/division.
- The number of clocks refers to the number of samples of the
- data from the input terminals which have been taken.
- Page 14-23 - The third paragraph discusses how to specify the
- number of samples stored before and after triggering. The user
- can also specify the number of samples by selecting the set
- button in the clock box of the logic analyzer and making the
- appropriate changes.
