How to check the result stored in the tab_c

[BiscuitsColonel]

Hello,

I tested test_q1.exe in the database library.
The following is the execution log.

In the test, I could confirm that the database library was working, but I could not confirm the result of executing the query with q1 of TPC-H.
I think the contents are saved in tab_c, but please tell me how to check.

The test code has a command line option -validate on to call software reference in q1.hpp and compare against FPGA result.

What I want to check is the contents of tab_c.
Is it possible to check what kind of result is stored in tab_c by referring to q1.hpp?
