+# NIAnalyzer
+
+## Programmable NIA analyzer and debugger
+
+Receives debug bus (NIA, val, advancing, count, tag bits) and counts various events:
+
+   * compare NIA vs all block specs (start/end) to match one or more blocks, or none (also counted)
+   * count 'advancing' (count is for multiple completions)
+   * could count 'valid and not advancing' cycles (latency); may only make sense for single ops
+   * tag bits could specify b/alu/rot/ld/st/spec/etc. or other info (icmiss, dcmiss, stall, byps, ...)
+   * could also be able to generate signal(s) based on events (stall/interrupt core when full), event seen, etc.
+
+
+* gen-configurable
+
+   * nia width, number of buckets, ...
+   * local bram size
+
+* csr-configurable
+
+   * buckets def
+   * ctls (start/stop/rst/...)
+
+* wb interface to connect to uart/eth/mem
