* | | | Fix assertion failure on invalid LOCATE input. | Gary Wong | 2020-04-05 | 1 | -0/+2 | |
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to parse this invalid LPF syntax: LOCATE COMP "a" SITE "A1" IOBUF PORT "a" IO_TYPE=LVCMOS33; (note missing semicolon on first line) gives an assertion failure in strip_quotes, because the fifth token is scanned as "A1"IOBUF (without a trailing quote). Avoid the problem by detecting extraneous input and issuing a more specific error. | |||||

* | | Remove comment about the USRMCLK primitive being untested. | Gary Wong | 2020-04-02 | 1 | -1/+1 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tested and verified working: the trivial configuration: module USRMCLK( USRMCLKI, USRMCLKTS ); input USRMCLKI, USRMCLKTS; endmodule module top( input clk ); reg[ 24:0 ] count = 0; always @( posedge clk ) begin count <= count + 1'b1; end USRMCLK mspi( .USRMCLKI( count[ 20 ] ), .USRMCLKTS( count[ 24 ] ) ); endmodule produces the expected output (toggling at high frequency, toggling tri-state at lower frequency) on an LFE5U-85 when fed with an appropriate clock. See https://bayimg.com/AAnNKAAGO for an example. The top (magenta) trace is the MCLK line. | |||||

* | | More adjustments to .bba file locations | Larry Doolittle | 2020-01-14 | 1 | -1/+1 | |
|/ | | | | | | | | | | Follows PM discussion with Marcus Comstedt. Extend changes in .bba file location (made in commit b6a7b60) to ice40 and MSVC cases, so all cases become compatible with read-only access to git tree. Only known down-side is inefficiency when building out-of-tree for multiple architectures; people following that use case should consider using PREGENERATED_BBA_PATH. It would be nice if there were less copy-paste in MSVC vs. non-MSVC content in family.cmake, but that would have to be addressed by someone more skilled in Cmake and MSVC. | |||||
