sim68xx - simulator for the 6800/6801/6303/6805/6811 family. Developed by Arne Riiber (1994 - 2004) <riiber at systek.no> Some additions, patches and H6303 architecture by Felix Erckenbrecht (2011) <dg1yfe at gmx.de> An archived version of the projetcs original homepage is available at http://www.oocities.org/thetropics/harbor/8707/simulator/sim68xx/ Directory structure: src Source files (*.c) inc Include files (*.h) doc Documentation test Test files for the simulator The executables are located in src/boards/. To produce the executables, enter the src/ directory and type make. If this does not work, see the documentation in the doc/ directory. Change log: Archive name Date and News sim68xx-2011.01 May 08 2011 (and before -> see Git History) Make code compile on OS-X Add HD6303 target Extend OPTAB for 6303 to include more adressing modes Removed support for MSDOS Include all missing interrupt sources for 6303 (OCF2, CMI, TOF, ICI) Include warning if return address changed during ISR sim68xx-0.9.9 May 02 2004 Fixes for 6811 disassembling after bug report from [email protected] - Corrected disasm INY/DEY (was "-") - Corrected disasm and cycles of LDY/STY - Adjusted display of CPD 0,X and CPD ffff sim68xx-0.9.8 Apr 08 2003 Enhancement of sim68xx-0.9.7: - Added support for TOC2-TOC5 for sim6811 requested by [email protected] sim68xx-0.9.7 Nov 11 1999 bugfix of sim68xx-0.9.6: - fix for sim6811 interrupt push order bug for A/B, reported by [email protected] sim68xx-0.9.6 Oct 15 1999 bugfix of sim68xx-0.9.5: - fix for sim6811 brclr bug reported by [email protected] - new brset/brclr test program test/arch/m6811/brtst11 sim68xx-0.9.5 Aug 20 1999 - Compiled on Win95 - Users Guide written - Cleaned up sim68xx-0.9.4 Dec 13 1997 - Fixed bug for trap 6811. - More robust load of .S19 files. - New programs simulating boards: sim_nc24re (6811E9) - Added display of triac/relay output for simnccpu - Added display of I2C-like commands (chip X924C) for simnccpu - Added user commands EXEC_FUNC_ON/OFF sending to SCI for simnccpu - Added system flag hints in src/Makefile for compiling and optimizing with (using GNU make): - Linux, SunOS 4, Solaris 2.x, GNU CC - SunOS 4, native cc - Solaris 2.x, native cc (SPARCompiler 3.0.1, 4.0.1) - SCO SYSVR3 cc - Added timing result for the simulator sim6301 to file test/arch/h6301/readme. Real 6301 use 1.0 seconds: - 2.8s 486DX25 Linux 2.0 gcc -O2 -finline-functions - 0.5s P90 SCO SYSVR3 cc -O - 1.2s SPARC20? SunOS 4 gcc -O2 -finline-functions - 1.7s SPARC20? SunOS 4 cc -O2 sim68xx-0.9.3 Oct 23 1996 No functional change. Removed break storage from command.c to memory.c sim68xx-0.9.2 Dec 19 1996! Functional: - compiling: - flags exported when make'ing - dependencies for executables now OK Structural: - moved src/*.c to src/base/*.c sim68xx-0.9.1 Oct 4 1996 Chip simulators: sim6301, sim6805, and sim6811. Board simulators: simncpan, simnccpu. - Doubled performance by inlining and macros. - Compiled under Linux only, not DOS or Sun. - Fixed 6805 spi bug (iregtab.c) - Documentation: - Performance analysis report (file: doc/performace). - GUI layout and possible implementations (file: doc/sim68xxtool.txt). GUI prototype (src/gui). - User guide: extending the simulator chapter written. - Unix man page (doc/linuxdoc/sim68xx.man) sim68xx-0.5.g Apr 2 1996 As sim68xx-0.5.e, plus: - Support for 6805 timer output compare - Sci output modes in ascii,\ascii,hex, io_poll - Buffalo 3.4/K4/D3 is a single checkout-able file - test/*/*.s19 files removed - Fixed bugs in 6811 SCI output and SPI, now OK. - Added Memory dump/modify command - Added repetition of last command on Enter key - Added list [symbol] command sim68xx-0.5.e Oct 9 1995 sim6301 (6800 compatible) and sim6811 simulator programs. - Simulator core passed through extensive test program (src/68xx/test/bigtst00.s19). - Many test programs in the test/ tree. - Added support for asm68xx symbol files. - Compiled/tested on platforms: - DOS 5 with Turbo-C 2.0 tcc and GNU make (sim6800). - Linux 1.1 with gcc - Solaris 2.4 with gcc and SUNWSpro - To make executables: DOS : cd src; gmake -f makefile.tcc Unix : cd src; make sim68xx-0.1.0 Jul 24 1995 6800 simulator only. - Restructured source tree so I/O can be reused with different chips in the 68xx family. - Automatic generation of *.h files. To make the single executable sim6800: cd src; make sim68xx-0.0.2 Jun 18 1995 Added support for: - symbol support (symtab.c,command.c) for aslink .map (6800.c,6805.c,6811a.c,callstack.c,command.c) - SCI input from keyboard (6811a.c, tty.c) - SPI support (6811a.c) - stack check for subroutine calls Bugfixed: - bset/bclr for indexed x (6811a.c) - idiv, fdiv (6811a.c) - clock cycles (6811a.c) New files: - symtab.c, tty.c To make executables: Type: make sim68xx-0.0.1 Apr 1 1995 Basic simulator for 6301,6805,6811 + 2 example boards. Character user interface commands: Run, Break, Disasm. Compiled on: Linux 1.1 and SunOS4 with gcc-2.5.8 To make executables: Type: make
