This is version 4.0 of the program Sim for simulation
of register-transfer-nets.
V4.0: - Now it's possible to define external devices.
For this purpose a C compiler is needed (Aztec).
V3.0: - Two new devices were added to the existing devices.
- REG_SET_P and
- REG_SET_N
Register sets (level triggered) with seperated read/
write addresses and in/outputs.
- Another bug fixed in the handle of the RESET gadget.
V2.1: - Bug fixed in the handle of the RESET gadget.
V2.0: - In the LAMP window a new gadget RESET was added.
With this gadget the simulator can be pushed back into the
state immediate after the program was loaded.
- In the translation of the VLI there is a check for leads
that are only used as outputs. This can be the succession
of misspellings in the VLI.
- Four new devices were added to the existing devices.
- JK_REG_P and
- JK_REG_N
J-K-registers with asynchronous set and reset inputs.
- PAT_GEN
Pattern generator of any binary pattern on a 16-bit-
lead.
- RECORDER
Recorder device. After the simulation the recorded
signals will be written to a file.
- The RAM-device was changed in its function.
V1.2: - The queue of the computable devices will be initialized
now in the correct way.
V1.1: - A stop condition was added as a new device.
With this device a simulation can be stopped at a specific
point.
