EDA Debugger
EDA debugger is used for debugging the calculation of calculated vectors and functions of the EDA subsystem. This feature is included in a group of graphic objects for pictures as an EDA debugger.
This graphic object enables, directly in its interface, to connect to any EDA calculation in the application. Calculation means loading of calculated vector or calculation of function. The whole process of debugging is controlled in the graphical interface, i.e. in the EDA debugger.
Another method of usage of EDA debugger is the initiation of calculation for debugging directly from ESL script. This method requires supporting functions of the EDA debugger. In the first step, the user must create a debugging connection with the process that executes EDA calculations. To establish this connection, use the function %HI_EDADebugOpen. The function %HI_EDADebugClose closes this connection. After creating debug connection, the user may start the calculation of the calculated vector for debugging by calling the function %HI_EDADebugVectorRec. When calling %HI_EDADebugCalcFunctionRec, it activates debugging calculation of the EDA-L formula. Functions %HI_EDADebugVectorRec and %HI_EDADebugCalcFunctionRec do not wait for finishing the calculation that was started by these functions.
Example of an EDA debugger that is used in a picture opened in HI:
It consists of:
Toolbar – contains buttons that represent debug commands.
Tabs with calculations – contains source formulas of vector calculation.
Messages – contains messages that have been generated during calculation.
Variables – contains monitored variables of selected vector.
Call stack – contains the current list of nested vectors of aborted calculation.
Toolbar
Buttons represent the commands that control debugging of calculations.
| Enable/disable the numbering of rows in the formula. |
| Go to row in displayed vector. |
| Connect to calculation – connection to running calculation which should be debugged. Dialog window displays the list of all running EDA calculations in the application with information such as on which EDA server the calculation runs, from which client was started, and the initiate vector that is calculated. EDA calculations |
| List of local variables in displayed vector - enables to add variables into Variable tab. |
| List of vectors used when debugging (closed vector included) – enables to open (select) vector which will be displayed. Selection of vector |
| The icon which informs about the status of calculation:
|
| Continue in the calculation. |
| Continue in calculation up to row with the cursor (if on the row is not any script command, calculation continues up to next row with command). |
| Step inside – if the row contains loading of the calculated vector, the process continues within it. |
| Step outside – if the row contains loading of calculated vector, loading is executed and calculation stops on the next row. |
| Continue up to return from the vector. |
| Abort calculation. |
| Stop calculation. |
| Aborted when occurring an exception – indicates two statuses differentiated by color:
|
| Delete all breaks in all vectors. |
| Finish calculation debugging (calculation will continue). |
Tabs with calculation
Tabs contains the vector formulas that were used when debugging connected calculations. Vector formula occurs in tabs automatically after aborting the calculation - tabs contain all vectors that are in the current call stack. Users may manually close (hide) the tab with the vector formula and then open it again (via the list of vectors).
Tabs show the name and version of the vector and indicate its status (3 options):
Grey circle – vector, at the time of aborting calculation, does not occur in the call stack.
Green circle – vector, at the time of aborting calculation, occurs in the current call stack.
Red circle – vector, at the time of aborting calculation, occurs in the current call stack and contains a command that will be executed.
Tab with vector formula
It contains:
Optional row numbering
Breakpoints – red circles
Mark for aborting the execution of calculation – green arrow
Vector formula with syntax highlighting:
key words and functions – turquoise color,
local variable – yellow color,
delimiters – white color.
Description of variable and its value (for one-element variables) with the cursor.
