Port Map Rules¶
port_map_001 (instantiation_006)¶
This rule checks the port map keywords have proper case.
Refer to the section Configuring Uppercase and Lowercase Rules for information on changing the default case.
Violation
PORT MAP (
Fix
port map (
port_map_002 (instantiation_011)¶
This rule checks the port name is uppercase. Indexes on ports will not be uppercased.
Violation
port map (
wr_en => wr_en,
rd_en => rd_en,
OVERFLOW => overflow,
underflow(c_index) => underflow
);
Fix
port map (
WR_EN => wr_en,
RD_EN => rd_en,
OVERFLOW => overflow,
UNDERFLOW(c_index) => underflow
);
port_map_003 (instantiation_025)¶
This rule checks the ( is on the same line as the port map keywords.
Violation
port map
(
WR_EN => WR_EN,
RD_EN => RD_EN,
OVERFLOW => OVERFLOW
);
Fix
Use explicit port mapping.
port map (
WR_EN => WR_EN,
RD_EN => RD_EN,
OVERFLOW => OVERFLOW
);
port_map_004 (instantiation_007)¶
This rule checks the closing ) for the port map is on it’s own line.
Violation
port map (
WR_EN => wr_en);
Fix
port map (
WR_EN => wr_en
);
port_map_005 (instantiation_020)¶
This rule checks for a port assignment on the same line as the port map keyword.
Violation
port map (WR_EN => wr_en,
RD_EN => rd_en,
OVERFLOW => overflow
);
Fix
port map (
WR_EN => wr_en,
RD_EN => rd_en,
OVERFLOW => overflow
);
port_map_007 (instantiation_022)¶
This rule checks for a single space after the => operator in port maps.
Violation
U_FIFO : FIFO
port map (
WR_EN => wr_en,
RD_EN =>rd_en,
OVERFLOW => overflow
);
Fix
U_FIFO : FIFO
port map (
WR_EN => wr_en,
RD_EN => rd_en,
OVERFLOW => overflow
);
port_map_008 (instantiation_024)¶
This rule checks for positional ports. Positional ports are subject to problems when the position of the underlying component changes.
Violation
port map (
WR_EN, RD_EN, OVERFLOW
);
Fix
Use explicit port mapping.
port map (
WR_EN => WR_EN,
RD_EN => RD_EN,
OVERFLOW => OVERFLOW
);
port_map_009 (instantiation_021)¶
This rule checks multiple port assignments on the same line.
Violation
port map (
WR_EN => w_wr_en, RD_EN => w_rd_en,
OVERFLOW => w_overflow
);
Fix
port map (
WR_EN => w_wr_en,
RD_EN => w_rd_en,
OVERFLOW => w_overflow
);
