Debug functions are controlled via the DEBUG_FLAGS parameter. DEBUG_FLAGS is a 32-bit integer where every bit controls a debug function. There are also symbolic names defined for every debug function in header files.
Recommended: Declare
DEBUG_FLAGS a single time in the testbench and set the same value for both software and
Verilog hardware model. For software use the API function
cam_arg_set_debug_flags
. For Verilog hardware set the DEBUG_FLAGS parameter on
the instance.Debug Flag | Description |
---|---|
CAM_DEBUG_NO_ERROR_MSG | Disable printout of software error messages. |
CAM_DEBUG_ARGS | Software echoes input arguments. |
CAM_DEBUG_VERIFY_WR | Software immediately reads back written data from hardware for verification. Mismatching data is reported with error message. |
CAM_DEBUG_VERIFY_SHADOW | 'get_by_response' and 'get_by_key' operations read data from hardware and verifies software shadow data |
CAM_DEBUG_VERBOSE_VERIFY | Enables printout of all verify operations, including correct compare. Applies to CAM_DEBUG_VERIFY_WR, CAM_DEBUG_VERIFY_SHADOW, and CAM_DEBUG_VERIFY_CONFIG. |
CAM_DEBUG_SKIP_MEM_INIT | Skip memory initialization, useful to speedup Verilog simulation. |
CAM_DEBUG_CONFIG | Enable printout of configuration parameters for both software and Verilog hardware simulation. |
CAM_DEBUG_KEY_MASKING | Enable error check for the presence of key value '1' in masked (wildcarded) bit position. Applies stcam and tcam input arguments. |
CAM_DEBUG_STATS | Enable statistics printout in the 'bcam_destroy' and 'stcam_destroy' functions. |
CAM_DEBUG_SEGMENTS | Software prints segment map for virtualized bcam (vbcam). |
CAM_DEBUG_SKIP_VERIFY_CONFIG | Skip verification of hardware/software configuration parameters. |
CAM_DEBUG_SET_COVER | Software prints heap and set cover information for tcam. |
CAM_DEBUG_CONFIG_ARGS | Software prints cam_arg values before creating the instance. |
CAM_DEBUG_HW_WR | Verilog hardware prints write operations. |
CAM_DEBUG_HW_RD | Verilog hardware prints read operations. |
CAM_DEBUG_HW_LOOKUP | Verilog hardware prints lookup operations. |
