gpsim is a full-featured software simulator for Microchip PIC microcontrollers
|
||
|
|
distributed under the GNU General Public License.
|
||
|
|
|
||
|
|
gpsim has been designed to be as accurate as possible. Accuracy includes the
|
||
|
|
entire PIC - from the core to the I/O pins and including ALL of the internal
|
||
|
|
peripherals. Thus it's possible to create stimuli and tie them to the I/O pins
|
||
|
|
and test the PIC the same PIC the same way you would in the real world.
|
||
|
|
|
||
|
|
gpsim has been designed to be as fast as possible. Real time simulation speeds
|
||
|
|
of 20Mhz pics are possible. A 'goto $' program runs at the same speed as a
|
||
|
|
25Mhz pic when simulated on my 400Mhz PII Linux Box. Of course, as you add
|
||
|
|
stimuli and begin interacting with peripherals, the performance drops. But
|
||
|
|
it's still fast!
|
||
|
|
|
||
|
|
gpsim has been designed to be as useful as possible (at least that's the
|
||
|
|
intent - honest). The standard simulation paradigm including breakpoints,
|
||
|
|
single stepping, disassembling, memory inspect & change, and so on has been
|
||
|
|
implemented. In addition, gpsim supports many debugging features that are only
|
||
|
|
available with in-circuit emulators. For example, a continuous trace buffer
|
||
|
|
tracks every action of the simulator (whether you want it or not). Also, it's
|
||
|
|
possible to set read and write break points on values (e.g. break if a
|
||
|
|
specific value is read from or written to a register).
