103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.
olivier.girard 4822d 09h /openmsp430/trunk/core/rtl/verilog/omsp_frontend.v
91 Fixed bug when an IRQ arrives while CPU is halted through the serial debug interface.
This bug is CRITICAL for people using working with interrupts and the Serial Debug Interface.
olivier.girard 4835d 04h /openmsp430/trunk/core/rtl/verilog/omsp_frontend.v
85 Diverse RTL cosmetic updates. olivier.girard 4858d 03h /openmsp430/trunk/core/rtl/verilog/omsp_frontend.v
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 5217d 03h /openmsp430/trunk/core/rtl/verilog/omsp_frontend.v
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.

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 5253d 05h /openmsp430/trunk/core/rtl/verilog/omsp_frontend.v
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 5253d 06h /openmsp430/trunk/core/rtl/verilog/frontend.v
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 5374d 08h /openmsp430/trunk/core/rtl/verilog/frontend.v
17 Updated header with SVN info olivier.girard 5400d 03h /openmsp430/trunk/core/rtl/verilog/frontend.v
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5435d 03h /openmsp430/trunk/core/rtl/verilog/frontend.v
