Avocado vs SmartDO

Avocado is a free, open-source PlayStation 1 emulator for Windows, macOS, Linux, and Android. It can load files including .cue, .bin, .img, .chd, .ecm, .exe, .psexe, .psf, and .minipsf by drag and drop. Listed save tools include save states, quick save and load, and rewinding by one second. It supports digital controllers, DualShock, and mouse input, with up to two controllers and no multitap. Audio support includes XA-ADPCM and Red Book, and graphics use OpenGL hardware rendering. The project lists support for Anti-Modchip and LibCrypt protected games; PAL LibCrypt games need additional .SBI or .LSD subchannel information. A BIOS from a real console is required and must be placed in the data/bios directory; BIOS selection is prompted on first run. The project is in early development, so games may not start or may crash soon after. It is single-threaded, and audio synchronized to NTSC 60 Hz can stutter in PAL games.

SmartDO is a multidisciplinary, multiphysics platform for automatic engineering design optimization. Its Direct Global Search can begin an optimization after setup with one button, without a design of experiments or manual sensitivity study. The maker describes S.A.F.E.D. and SmartLearning as features that can bypass failed CAD or CAE runs and use earlier calculations to reduce computational cost. APO supports synchronous multi-objective optimization without user weighting. SmartDO uses Tcl/Tk and Python, allowing add-ons, GUIs, graphics, and plotting tools. SmartLink connects the platform with CAE packages, while OpenXim links commercial or open-source CAD with simulation software. Named examples include ANSYS Workbench, FreeCAD, SOLIDWORKS, NX, PrePoMax, and CalculiX. The software page reports successful use with more than 240 design variables and 132 constraints. FEA-Opt Technology develops SmartDO and offers consulting and integration services. Pricing is available on request.
