While free vendor toolchains are generally used by beginners or for prototyping
|
2013-02-22 08:28:05 -05:00
|
|
|
(situations where having a logic analyser in the design is generally very
|
|
|
|
|
helpful) free toolchains are always provided without the proprietary logic

Based on Migen, miscope aims to provide a free, portable and flexible
|
2013-01-21 16:40:36 -05:00
|
|
|
alternative to vendor's solutions!

|
|
|
miscope provides Migen cores to be embedded in the design and Python drivers to
|
|
|
|
|
control the logic analyzer from the Host. miscope automatically interconnects
|
|
|
|
|
all cores to the CSR bus. When using Python on the Host, no needs to worry about
|
|
|
|
|
cores register mapping, importing miscope project gives you direct access to
|
2013-01-21 16:40:36 -05:00
|
|
|
all the cores!

|
miscope produces.vcd output files to be analyzed in your favorite waveform viewer.
