Hunter Nichols 60088c2dfb Added changes to lib to allow the default to run. Will crash with multiport options. 2018-08-31 00:42:56 -07:00
Hunter Nichols 5989a3c952 Expanded run_delay_stimulas to multiport. Bug Fixes as well. 2018-08-30 17:08:34 -07:00
Hunter Nichols 4b515fe1ac Changed create_test_cycles to have targeted ports for characterization rather than all ports always. 2018-08-29 17:16:11 -07:00
Hunter Nichols 775fe7b57c Fixed measure statement stating times. This commit crashes if there are no readwrite ports. 2018-08-29 15:13:31 -07:00
Hunter Nichols 8fad81ff1e Changed delay measures to add additional measure based on # of ports. Measure times are not correct yet. 2018-08-29 00:43:27 -07:00
Hunter Nichols fa8434e5f0 Added debug checks for unsupported port options. 2018-08-28 13:01:35 -07:00
Hunter Nichols bd763fa1e3 Fixed naming issue between sram instance and PWL in stimulus 2018-08-28 12:09:02 -07:00
Matt Guthaus bc67ad5ead Fixed timing to be measured from positive clock edge since 
reading a 1 will be the precharge time.
Started modifying the lib file for DIN and DOUT ports, but did not
check the syntax yet.

Matt Guthaus b88947ef5c Pass the sram design to lib instead of the sram wrapper 2018-07-18 11:51:42 -07:00
Matt Guthaus 0701fceb0b Use sram rather than new meta-sram class in the characterizer for delay 2018-07-18 10:39:29 -07:00
Matt Guthaus a2d8d16c7a Split DATA into DIN and DOUT in characterizer 2018-07-11 14:19:09 -07:00

Major changes:
Remove mpmath library and use numpy instead.
Convert bytes to new bytearrays.
Fix class name check for duplicate gds instances.
Add explicit integer conversion from floats.
Fix importlib reload from importlib library
Fix new key/index syntax issues.
Fix filter and map conversion to lists.
Fix deprecation warnings.
Fix Circuits vs Netlist in Magic LVS results.
Fix file closing warnings.
