Param2D
Param2D ?
• Param2D is a method to calculate value in ASCET with two input
values (x , y), just as a mathematic function
• Param2D is treated as a Local Parameter
How to Recognize Param2D ?
• Param2D is recognized by getAt function with two input parameters
• Param2D have three values:
• Input x (Input x varies between a (MIN_X, MAX_X) range )
• Input y (Input y varies between a (MIN_Y, MAX_Y) range )
• Output Value (Param2D output value is adjustable if it isn’t non-calibration  Normal and
Calib Table)
Param2D Coverage Requirement
• To cover Param2D, you have to cover 11 input points with two output
value tables
• Normal Value Table (Provide 9 input points):
1. x < MIN_X and y < MIN_Y
2. x > MAX_X and y < MIN_Y
3. x > MAX_X and y > MAX_Y
4. x < MIN_X and y > MAX_Y
5. x = MIN_X and y = MIN_Y
6. x = MAX_X and y = MIN_Y
7. x = MAX_X and y = MAX_Y
8. x = MIN_X and y = MAX_Y
9. MIN_X < x < MAX_X and MIN_Y < y < MAX_Y
( MIN_X <= Param2D Input x <= MAX_X )
( MIN_Y <= Param2D Input x <= MAX_Y )
• Calib Value Table (Provide 2 input points):
10. x = MIN_X and y = MIN_Y
11. x = MAX_X and y = MAX_Y
Purpose: Param2D Parameter have minimum and
maximum of output value
Param2D Required Point
Note
• Testcase covers Param2D must run through interpolation code
• The ASCET_INTERPOLATE_ROUNDED problem occurs in every
Param2D test project and it is uncoverable.
• Testcase covers Param2D must be commented with Param2D cover
point requirement role.
• Param2D table mustn’t appear in Imported Parameters section.
Example
• Step 1: Add Parameter Name and max, min, tolerance properties
• Step 2: Find Param2D Normal data table
• Step 3: Create Param2D calib data table
• Step 4: Fill Param2D Normal required points (9 points)
• Step 5: Fill Param2D Calib required points (2 points)
• Step 6: Ensure testcases cover Param2D run through the interpolation code
• Step 7: Comment Param2D testcases
• Step 8: Create test project and Import data
• Step 9: Alter *.dcm files for testcases that use calib data table
• Step 10: Run project
