Eclipse Webmaster requested to merge github/fork/OttG/sb_full_fix into master Jan 24, 2022

Created by: OttG

The scoreboard issue counter issue_cnt_q and issue_cnt_n have length equal to log2(NUM_ENTRIES) - 1 where NUM_ENTRIES is the number of scoreboard entries. In the standard case where NUM_ENTRIES = 8 the counters are 3 bits long meaning that they can count from 0 to 7 making it impossible to use the full scoreboard (always leaving one spot free).
