X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=70b53794105a5c7bc3ddba1712f471dd01a81dfe;p=multi_sim.git

Add /8085/blocks.png which manually separates the chip into any obvious blocks, change /conn_matrix.txt and /Makefile to include blocks.png in the analysis (it will generate reports to indicate the association between channels and blocks)
