2.8.4. In-System Sources and Probes Service
ISSP Service
Before you use the ISSP service, ensure your design works in the In-System Sources and Probes Editor. In System Console, open the service for an ISSP instance.
set issp_index 0 set issp [lindex [get_service_paths issp] 0] set claimed_issp [claim_service issp $issp mylib]
View information about this particular ISSP instance.
array set instance_info [issp_get_instance_info $claimed_issp] set source_width $instance_info(source_width) set probe_width $instance_info(probe_width)
The Intel® Quartus® Prime software reads probe data as a single bitstring of length equal to the probe width.
set all_probe_data [issp_read_probe_data $claimed_issp]
As an example, you can define the following procedure to extract an individual probe line's data.
proc get_probe_line_data {all_probe_data index} { set line_data [expr { ($all_probe_data >> $index) & 1 }] return $line_data } set initial_all_probe_data [issp_read_probe_data $claim_issp] set initial_line_0 [get_probe_line_data $initial_all_probe_data 0] set initial_line_5 [get_probe_line_data $initial_all_probe_data 5] # ... set final_all_probe_data [issp_read_probe_data $claimed_issp] set final_line_0 [get_probe_line_data $final_all_probe_data 0]
Similarly, the Intel® Quartus® Prime software writes source data as a single bitstring of length equal to the source width.
set source_data 0xDEADBEEF issp_write_source_data $claimed_issp $source_data
The currently set source data can also be retrieved.
set current_source_data [issp_read_source_data $claimed_issp]
As an example, you can invert the data for a 32-bit wide source by doing the following:
set current_source_data [issp_read_source_data $claimed_issp] set inverted_source_data [expr { $current_source_data ^ 0xFFFFFFFF }] issp_write_source_data $claimed_issp $inverted_source_data
