Merge pull request #1520 from pietrmar/fix-1463 
coolrunner2: remove spurious log_pop() call, fixes #1463
 2019-11-22 22:45:40 -08:00
Martin Pietryka 97b22413e5 coolrunner2: remove spurious log_pop() call, fixes #1463 
This was causing a segmentation fault because there is no accompanying
log_push() call so header_count.size() became -1.

Merge pull request #1449 from pepijndevos/gowin 
Improvements for gowin support
 2019-11-19 17:29:27 +01:00
Pepijn de Vos 8ab412eb16 Remove dff init altogether 
The hardware does not actually support it.
In reality it is always initialised to its reset value.

Marcin Kościelnicki 15232a48af Fix #1462, #1480. 2019-11-19 08:57:39 +01:00
Marcin Kościelnicki 7a9081440c xilinx: Add simulation models for MULT18X18* and DSP48A*. 
This adds simulation models for the following primitives:

- MULT18X18 and MULT18X18S (Virtex 2*, Spartan 3)
- MULT18X18SIO (Spartan 3E, Spartan 3A)
- DSP48A (Spartan 3A DSP) — implemented in terms of DSP48A1
- DSP48A1 (Spartan 6)

whitequark 3c643c57df write_verilog: add -extmem option, to write split memory init files. 
Some toolchains (in particular Quartus) are pathologically slow if
a large amount of assignments in `initial` blocks are used.
