60 Cleanup of the PC (R0) generation logic.
Formal equivalence was shown between the new and old code with Synopsys' Formality (to make sure that nothing has been broken :-P ).		 olivier.girard 5271d 09h /openmsp430/trunk/core/
58 Update the debug hardware breakpoint verification patterns to reflect the latest design updates. olivier.girard 5273d 07h /openmsp430/trunk/core/
57 Update design to exclude the range mode from the debug hardware breakpoint units. As this feature is not used by GDB, it has been disabled in order to improve the timings and save a bit of area/utilisation.
Note that if required, this feature can be re-enabled through the `HWBRK_RANGE define located in the "openMSP430_defines.v" file.		 olivier.girard 5273d 07h /openmsp430/trunk/core/
56 Update Design Compiler Synthesis scripts. olivier.girard 5277d 14h /openmsp430/trunk/core/
55 Add a "sandbox" test pattern to play around with the simulation :-P olivier.girard 5278d 09h /openmsp430/trunk/core/
54 Update FPGA projects with the combinatorial loop fixed. olivier.girard 5278d 12h /openmsp430/trunk/core/
53 Fixed the following combinatorial timing loop:
1- irq_detect (omsp_frontend)
2- decode (omsp_frontend)
3- dbg_swbrk (omsp_dbg)
4- halt_flag_set (omsp_dbg)
6- dbg_halt_cmd (omsp_dbg)
7- irq_detect (omsp_frontend)

Without this fix, problem could occur whenever an IRQ request arrives during a software breakpoint instruction fetch.		 olivier.girard 5278d 12h /openmsp430/trunk/core/
37 olivier.girard 5307d 09h /openmsp430/trunk/core/
34 To avoid potential conflicts with other Verilog modules in bigger projects, the openMSP430 sub-modules have all been renamed with the "omsp_" prefix. olivier.girard 5307d 11h /openmsp430/trunk/core/
33 In order to avoid confusion, the following changes have been implemented to the Verilog code:
- renamed the "rom_*" ports and defines to "pmem_*" (program memory).
- renamed the "ram_*" ports and defines to "dmem_*" (data memory).

In addition, in order to prevent potential conflicts with the Verilog defines of other IPs, a Verilog undefine file has been created.		 olivier.girard 5307d 12h /openmsp430/trunk/core/
23 Renamed the "openMSP430.inc" file to "openMSP430_defines.v" & added the "timescale.v" file.
In order to follow the same structure as other OpenCores projects, the timescale and the defines are now included from within the Verilog files (using the `include construct).		 olivier.girard 5428d 14h /openmsp430/trunk/core/
19 added SVN property for keywords olivier.girard 5454d 08h /openmsp430/trunk/core/
18 Updated headers with SVN info olivier.girard 5454d 08h /openmsp430/trunk/core/
17 Updated header with SVN info olivier.girard 5454d 09h /openmsp430/trunk/core/
6 Some more SVN ignore properties... olivier.girard 5476d 10h /openmsp430/trunk/core/
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5489d 09h /openmsp430/trunk/core/
