I am using CONCEPT HDL version 16.5. When i define the property 'has_fixed_size' in the symbol property, an error message is displayed suggesting that 'has_fixed_size' is a reserved property and cannot be user defined. And when i enter the property in the part table key properties and specify a value for it the following error is displayed while saving "cannot find a ppt part that matches the instance properties"
So is there any way to define a user defined value for the property 'has_fixed_size'
Thanks in advance.
