    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

class mypixels;
 
  typedef enum {R, B, G, D} colors;
 
  rand colors c;
  rand int pixels[7][7];
 
  constraint valid_colors { foreach(pixels[i,j]) pixels[i][j] inside {R,G,B,D}; }
 
endclass

this code will return numbers 0,1,2 and 3. I want each [i][j] to be filled with R,B,G and D and actually use my enum.

Thanks
Kimiya

In reply to verif_girl:

Then declare pixels with the colors datatype instead of an int. You won't even need the constraint anymore.

Thank you very much Dave.
Is there a way for me to access each element of array in a constraint if let’s say I don’t want to have more than 10% of colors to be blue “B”? Thx

In reply to verif_girl:

Use the sum () array reduction methods

constraint limit_blue { pixels.sum(row) with (row.sum(col) with (int'(col == B))) <= 7*7/10; }
